Uh oh! This is one of the dangers of these dang radicals.
First of all, the radicals are *not* intended to be used as
regular ideographic characters. That is why they all have the "So"
property, rather than "Lo". So if you go around recommending their
usage *instead* of the unified character for regular text, you
can end up with some strange behavior.
Note that the entire Kangxi radical set, U+2F00..U+2FD5, are
duplicate symbols for the radicals that *are* encoded as unified
characters in the main set. Effectively, they are all compatibility
The CJK radicals supplement, U+2E80..U+2EF3, are the ones that
show a number of specific forms, but those are intended for
special text purposes, as when specifying a radical index in

First of all, you missed the simplified version of 'teeth'
at U+9F7F. If someone explicitly wants the (Chinese) simplified
version, of course they should use that, and not U+2EEE, for

I think you are way overstating the scope of the problem.
Browsers can meet most of their users expectations merely by
having their Unicode font set to a Japanese font or a Chinese
font, as desired. It is only for fine control of mixed
language data that you may need more, and for that, it is
not unreasonable to expect that people will require language
and font markup.
I consider it pernicious to be suggesting that things would
be better if we just gave up on unification and encoded all
the glyphs. You might make things a little easier on the
rendering end (although the fonts would keep growing), but
the resultant problems of text equivalence for searching and
other text processes would just get much worse than it already
is for Han characters.
