I don't think the capability to unload and reload is a necessary
requirement from any Emacs feature. In particular, unloading a
feature is not always supported in a way that leaves a clean slate.
It is a good thing to have that, no doubt. But not a hard
requirement, IMO. Especially when the grammar is a C library, not a
Lisp library. People who are testing grammars are advised to use
scratch Emacs sessions which are restarted when the grammar changes.
