Why not add this to greek.el?

Is this a good idea?  It seems to go against the intent of whoever is
typing the text: they do want the decomposed characters to appear in
the text.  Emacs will automatically (by default) compose them on
display (and if it doesn't, that's a bug that should be reported and
fixed), per Unicode requirements, and if the font supports the
precomposed glyph, you will actually see that glyph on display.
Replacing characters with their NFC equivalents should IMO be a
separate feature, not something an input method does.  Am I missing
something?

Thanks.
