The simple answer to that question is no.

There is a similar page which is somewhat less obsolete, even if also that one needs to be updated:

https://help.ubuntu.com/community/ComposeKey

But such tutorials are user contributions, and there is no team or individual who is responsible for maintaining them. So what you can do is applying to get edit access and try to improve them yourself.

https://help.ubuntu.com/community/WikiGuide#Contributing

I'm inclined to think that <https://wiki.ubuntu.com/ComposeKey> should be deleted and the other page updated.

Given that Ubuntu is now on GNOME, which relies on IBus to a large extent, IBus will keep being default.

XIM is old, sometimes problematic (see e.g. bug #1573755), and will probably be dropped completely if/when Ubuntu switches from X to Wayland.
