I have a dim recollection, which may be wrong, of one of the Research folks
saying "we dropped that because it was too hard to keep the precompiled
versions up to date with troff".

Also, my recollection is that you couldn't precompile just any macro package;
because of the odd way it was done, the package had to comply with some
non-trivial restrictions on the order of operations.
