The request was for an environment similar to Genera, not an optimal environment for deploying to consumer systems. While it may work quite well for the latter, it fails at the former.

I don't see how you read that from behnamoh's comment. The 'request' or rather confusion was that the only way to do Lisp, historically and now, is with proprietary stuff like Genera or more modernly LispWorks, so what's there to do if someone wants to get into it now. On the contrary, I pointed out if anyone wants to get into Lisp now, in 2023, there is also amazing free tooling that's very capable just like many other languages for building and doing the sorts of things people typically want to do in 2023. The only other part of the comment I didn't address was just my agreement that proprietary emphasis did hurt Lisp adoption, though not getting Quicklisp until as late as 2010 hurt it more. Things don't seem so gloomy now these last several years at least.
