I use XKB specifically to enter non-ASCII characters: accented
characters (either with a direct mapping to the Unicode character
or via a dead key), Greek letters (via a dead key) and math symbols
(either with a direct mapping to the Unicode character or via the
compose key). But at the end, I always get a single Unicode character
(I do not need to handle combinations of Unicode characters).
These where things that one could mostly do for years, even before XKB
(e.g. with xmodmap), though xmodmap had additional limitations with
some keys.
It seems that the issues mentioned in
https://bugzilla.redhat.com/show_bug.cgi?id=2013610
concern input methods that are not possible with XKB (at least I'm
not aware of).

I've tried xfce4-terminal and lxterminal and they have the same issues
as gnome-terminal.

For xterm, this is due to a change in libfreetype6
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=866960
(I've patched xterm, but this is rather ugly because this depends
very much on the font and its size, and I finally think that this
should become a preference). I'm not sure whether this is the same
cause for the other terminals, because the libfreetype6 developers
recommend to use the unrounded metrics, which xterm doesn't do. In
xfce4-terminal, allowing the vertical cell spacing in the terminal
preferences to be slightly less than 1 might solve the issue if
this is supported internally.
Concerning the mouse wheel (bug reported for gnome-terminal):
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=921537
and this cannot be disabled (ditto with xfce4-terminal at least):
