I see that Franz has implemented some extended form (as allowable by the
CLtL2 definitions) with some documentation here —
and SBCL notably has a test suite for their implementation — in

I believe I can speak on behalf of the maintainers if I say that ECL has
very little resources (i.e. programmer time) available, and it is not very
likely that someone will be able to devote time to such a feature request
until or unless it's needed by their own projects; thus, while perhaps one
of them might be able to do so in fewer hours, those hours are likely to be
months, or years, away.

Perhaps if anyone more knowledgeable about ECL's internal environment
structures and evaluation systems would care to provide some pointers on
this thread, then perhaps that would assist you in your goal?
