Aw, a fan. :-)
I'm quite sure, from the design problems (they're not bugs), that none of them spend any appreciable time on mailing lists, or different design decisions would have been taken at pivotal points.
As I noted, you can get bottom quoting for the price of 2 blank-line deletions; I hard wrap by hand, and rewrap quotes when necessary.
It is, yes, a cast iron pain in the ass, but since the "can't read forwards" bug is reducing my participation in general -- and I'm insanely busy with 2 workstation refresh rollouts at work -- it's been less pressing to me.
As you may have noted, I've filed about 35 bugs; these are my most prominent issues (along with RFC 2369 support). I encourage the 2 or 3 of you out there that I know about who understand these issues, and care, to vote for the appropriate bugs in the list above (if my bug was duped onto someone else, and I didn't yank it back off, vote for the older bug).
If they get 50 or 100 votes, they'll get some of this stuff done.
A complete list of the bugs I personally have opened is
here.
If you're a commercial licensee, note your seat count in a comment on the bug after you vote; money talks, too.
