This seems to be a general consensus for behavior during input for a lot
of languages.

Doing this editing, doing this is relatively easy, since it can at the
input method level.  The main disadvantage is that languages that
otherwise don't require an input method (like Tamil) would then
require an input method. But an input method can also provide the
additional advantage of prohibiting the entry of invalid sequences,
when the language has such.

The other half of the question is whether it should be possible to delete
the last character in a grapheme when editing existing text, or whether,
in that case, delete should delete the entire cluster.
