I don't, but I also don't like the present short rest system, because it makes short rests too hard to come by for classes that depend on them.
What I would really like would be a return to 4E-style short rests: Five minutes and done. But this would require a wholesale rewrite of the short-rest classes, who would otherwise be grossly overpowered (e.g., the 5th-level warlock who can now throw two fireballs every single combat). That's almost certainly out of scope for 5.5E.
"5-minute short rests, prof bonus times/day" is a bit of a hack, but it works well and doesn't require major changes to the rest of the system. My table uses essentially this house rule (except we use a flat 2/day instead of prof bonus), and it neatly and easily brought the short-resters up to par.
