esoteric is a negative for deployment your opinion is bad
supported platforms esoteric doesnt take away from deployment https://clisp.sourceforge.io/impnotes/clisp-history.html
only a argument when the independent code is a unmaintainable monstrosity
while GNU Common Lisp is essentially unmaintained since 2014
you would of had a more valid argument pointing out how its maintained by one person with the last release 9 months ago
real argument if you could point out the exacts of where it fails the ansi common lisp standard Yes or how this one person couldnt do maintenance with the foundations
and this one person couldnt or forgot to close bugs https://savannah.gnu.org/bugs/?group=gcl
clisp also has a history of not supporting ansi https://clisp.sourceforge.io/impnotes/faq.html#A.1.1.4. its not lgpl either which means something for a minority vocal about deployments
