Because non-Emacs apps don't have LEIM and LEIM in Emacs is more convenient
that system-wide `xkb', because with `xkb' there was no way to type `M-d'
in Russian layout, it would work as `M-в' instead.  OK, I see now there is
(just checked), but still there is no way to use things like `C-x t' when
using `xkb' Russian layout (`C-x е' instead.)

I'm ranting about LEIM not reacting to Mode_switch.  In fact, Emacs simply
ignores the modifier.

Yeah, but `xkb' handling in Emacs has more significant disadvantages, see
above.

See above.  I'm using LEIM because it is more convenient, but it lacks one
specific feature compared to `xkb'.
