This might sound a bit weird, but Mutt for example tackled this problem
by having (in threaded mode) a "strict_threaded" flag, that toggles
trying to do (some intelligent) subject matching, or only looking at
In-Reply-To headers.

I find that almost any email client these days sends proper In-Reply-To
headers, and hence, strict threading works fine (and if it doesn't, Mutt
of course allows to manually join and break threads).  So, I also think
subject matching is not necessary any more.
