Probably means they weren't very good to begin with.
Heh. That's a bit harsh, but also true more often than not.

Same here, but I know how perilous it is to design interfaces without a concrete and obviously useful application from the start so let's be careful.
I agree. Here's an obviously useful application in my humble opinion: to turn on Elisp's Flymake checker by default.
To do that, we must ensure that this checker, which starts an emacs inferior process to byte-compile Lisp code, is guaranteed not to cause unintended side-effects.
This inferior Emacs macro-expands macro calls and thus and runs code: there's no other way to compile Lisp code. It must thus not be allowed to do "unsandboxy" things like writing to the file system or network. Probably also not starting other processes. But probably it should be allowed to cons lists and intern symbols inside its address space.
