I see that Franz has implemented some extended form (as allowable by the CLtL2 definitions) with some documentation here — http://franz.com/support/documentation/current/doc/environments.htm
and SBCL notably has a test suite for their implementation — in contrib/sb-cltl2/tests.lisp

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?
