That ship sailed a long time ago.  Emacs on Windows supports Unicode
keyboard input on Windows NT and later since Aug 2012, and Emacs 24.3
was released with that feature.  (This is limited to GUI sessions,
since Unicode support in Windows console applications sucks big time,
so much so that I consider it a waste of time and effort to support
that in text mode.)

This is inaccurate for the current Emacs: ToAscii is only used on
Windows 9X, where Unicode keyboard input is not supported.

Not sure what is this about; please elaborate.

We do use ToUnicode (on NT and later).

What version did you look in?

(This is not the best place to ask about Emacs development plans,
btw.)
