Hot potato, rat hole, religious crusade... take your pick.

There are developers that build HotSpot with FDS disabled because
the link phase takes longer than it used to. I have pointed out
that when they do that, their testing may not be valid since the
official push via JPRT or the official promotion from RE will
be built differently.

Some day we may get to the point where FDS-enabled is just the way
we build, but we aren't there yet.
