> Pretty sure that if you use replies or threads in Matrix when talking in an IRC channel, then people on IRC won't see them as replies or threads.

Replies are rendered to IRC with a prefix indicating what they're responding to, but people from IRC cannot "reply" (though maybe some ad-hoc protocol could be devised for this). I don't know if threads are handled the same way, but I assume they are. Of course you can't really bring either of these features to a platform that doesn't support them without modifying the platform.

By "other servers" I meant other Matrix servers, as it is the system that natively supports the features.

Matrix could bridge tem as IRC replies so at least IRCCloud users could see/write them, but are not interested in supporting them for now: https://github.com/matrix-org/matrix-appservice-irc/pull/150...
