To cut a long story short: the problem hasn't progressed.

However, your analysis is entirely correct: defining a macro for the
TRULY-THE form would indeed by the short term solution. My thoughts would
be to remove the special form longer term. Even though we have
special-purpose compilation support for it, I don't see benefits in keeping
it around. It's supposed to allow increased performance for compiled
programs. So, upon removal, we probably need to verify that the performance
degradation is small enough.
