We were clearly in the process of deleting the
member decleration to just have the decleration be in the constructor.
When we were distracted, leaving a property named `readonly`, which
shouldn't be possible imo, need to add some rule for that prompto.
We've done this to make the implementation a lot cleaner and
managable. However, we've taken the opportunity to simplify
all of the client code that would use this method.
Some of these simplifications might come at a small cost.
Updating server ACL, member bans and checking power levels
would all be clearly titled as seperate checks.
However, it should still be obvious what has gone wrong,
since any error would have to give a more detailed explanation.
And not everything is going to fail all at once (and if it does,
there are bigger issues).
a lot cleaner
