Yes, but SYMBOL-MACROLET is relatively common in Common Lisp programs, which in itself warrants its inclusion in a Common Lisp emulation library, IMO. And it being one of the macros that Common Lisp programmers writing Emacs customizations often reach for, I hope it will not be deleted. Plus, the effects of cl-symbol-macrolet will only apply inside BODY, so it can't do anything to the majority of code that doesn't use it. Thanks.
