This is not the case, Matrix rooms can be set to allow viewing history only from joining time on. And that is how IRC bridge rooms are mostly configured, indeed based on policies from the bridged IRC networks.

Ah ok I remember this was a problem that was mentioned by the hackint network when people wanted to add a bridge there. We moved our community to OFTC as a result.
Perhaps this was only introduced later? I'm talking about 3 years ago. But good to see this was fixed.
The clean rooms approach is a good thing I think. Xmpp is becoming a pileup of different add-ons and suffers from the same issues you mention for matrix (not all features supported by all clients). Probably in a worse way.
I know the reluctance of IRC operators to allow (global) matrix bridges is often a case of different paradigms. On IRC a conversation can only be seen by users who are present at the time. A user joining a bridged matrix room can see the entire history from before they joined. This changes the privacy model a lot (insofar as IRC has any semblance of privacy, but whatever is there is regarded as very important). People running their own Heisenbridge puppeting bridges solves this issue though.
I'm not a matrix dev but I do like it, especially the phenomenon of bridges.
