Hm, well, I think, yes.  But don't complain at me if there is some
corner case where that simple rule is not correct.

I think, especially with paredit.el, it should be quite easy to produce
a keyboard macro for doing that.

Well, yes.  Commas are only to be replaced in backquoted forms, but
since that's the only use anyway...

Nope, it's purely syntactical.
