None of the ones I have tried come even close to UX of pretty much any desktop IRC client.
So went with a more native TUI application (gomuks) and didn't really enjoy that either (scrolling broken, weird mouse behavior, unread messages got stuck on some channels and in other rooms it didn't show any unread messages at all, stuck room that I already left and some other issues that annoyed me).
Then I thought I give some desktop applications a go (quaternion, spectral, nheko, mirage and last I tried was neochat) and they fell into roughly two categories: ok-ish UX but too buggy to be usable or work but have UI designed for mobile but on desktop (which is a no-go for me).
That's where I am with my quest for a decent matrix client. I haven't tried _all_ desktop clients yet, but there are not that many non-electron/browser based ones left I think.
Catgirl, or some patched mpu irc.
That is, I'm sure it makes sense for them, and for most of their actual users, because Rust is nice, but if I have an m68k machine, too bad, there is no Rust for m68k (unless I'm reading the platform support chart wrong) and so this rewrite likely orphans me.
Now, if for a Debian channel, even a Debian channel about an attempt to port Debian to m68k, then I have no doubt your users all have something less stupid, maybe ARM or x86-64 or even PowerPC. They prefer a non-GUI for their own reasons but ultimately Matrix is an option.
But if you're a channel for actual m68k "classic" Amiga you might actually have a non-trivial number of users for whom "it doesn't run on m68k" is a showstopper. They have an IRC client today.
Rust doesn't target barely-capable archaic platforms like Motorola 68xxx or 80286 and I don't think it should start. But that means we have to accept that a Rust client won't support those platforms.
I doubt it would perform well even if you did get it running.
So this isn't a change in platform support.
