I was going to respond that to break the relationship between COMP_POINT
and rl_point makes it very difficult, if not impossible, to identify the
character under the cursor when completion is attempted, but I'm not
sure how much that actually matters.  You can't assign rl_point using
this, so that's not an issue either.

Pretty much everything else in bash uses characters, which may be bytes
depending on the locale.

Can someone who's more familiar with the bash completion package tell me
whether or not it uses COMP_POINT at all?  That's about that only thing
I can think of that would use it.
