No, the major reason for it is that flex 2.5.31 is seriously broken and
non-compatible with its prior releases.  I wasn't aware that they'd gone
so far as to remove a documented macro (one that was documented in 2.5.4
as the *preferred* way to do things, mind you) but we already knew of
several other issues with it.  See the archives.

I'll try to snarf a copy and see if there's a way to do it that's
compatible with both releases, but it's the flex authors' own fault
that 2.5.31 has had such poor uptake.
