Otherwise if the user has multiple clients doing incremental sync, they wont get their own profile updates to their other clients. For initial because it should probably match the incremental behaviour + it avoids clients needing to look up the profile separately potentially.
Change `/org.matrix.msc3814.v1/dehydrated_device/[device_id]/events` to
accept GET requests instead of POST.
The original version of
[MSC3814](https://github.com/matrix-org/matrix-spec-proposals/pull/3814)
said we should delete keys after returning them from this endpoint, but
it is being updated to say we should not delete them, and therefore the
appropriate verb is GET.
Synapse already doesn't delete anything, so we just need to change to a
GET with a `next_batch` query param. (Currently it is a POST with
`next_batch` in the JSON content.)
This code was initially written by @ara4n and Claude, but both he and I
have read it and think it makes sense. I am far from a Synapse expert,
so feel free to tell me it's all wrong and point me in the right
direction.
I don't know what system tests will be affected by this, but I guess we
will see when the CI runs (right?).
This is a change to an unstable endpoint so no need for notifications
about breaking changes or similar.

Instead of using replication when setting field values, remove that replication, keep writing the field via the profile handler in the current instance, and then dispatch recording the profile update over replication, if needed.
This is cleaner as it ensures we don't need to wrap various places outside the profile handler that set things like the displayname in the "if profile worker else replication" logic.
I believe the correct type is `JsonValue | dict[str, JsonValue]`, except deep down in the displayname/avatar_url store methods.
Removes a dubious cast by correctly casting in `get_profile_data_for_users`
This reports the total count of users (split by appservice) which is
meant to be the monthless counterpart to the MAU metric.
Context:
> So this is largely for billing purposes and wanting to know the change
in the number of users. If a user is deactivated then we no longer want
to count them. Consumers *might* want to count appservice users, and
maybe count them based on the service (perhaps you change more for users
under bridge X or bridge Y).

Didn't add the "safety" table due to afaik that has more relevance with the device updates, and not so much here for the profile updates.
After looking into it, just a couple of things to pick a bone at in the
old wording,
which I thought could be clarified for when I next come to look at this
again.
- the claim that there's a fundamental difference; I'd argue there isn't
really, it's just by convention
on some mainstream distros. So I have changed this to 'typically'
- statements that some distros fetch dependencies at build time
(probably does happen, but
traditional distros make a point of not doing this for the reasons you'd
expect).
- This was probably meant to be talking about Debian, but my observation
based on sample size of 3 is that some crates are packaged natively,
others are vendored in the respective application's source package (like
they do for us) and sometime they patch the bounds a bit
There could probably be room to talk about how distros vendoring
packages is a maintenance burden on them,
but I guess it's a bit moot as we would struggle to conform to wide
enough bounds to make everyone
happy (and anyway; I expect the distros that vendor packages have the
tooling to make this easy to
update and we do keep on top of security updates and release
frequently...)
