Perhaps the software should have a "metastability" tag for
signals between FFs that should be placed right next to each
other.  Then the timing analysis could tell you the slack
which is what you really want to know.  There are probably
other good things smart software could do with that info.

Or maybe that's a wild goose chase.  Maybe you don't want
them right next to eachother and the clock is slow enough
so it doesn't matter...
