What implementation complexity are you thinking of? The JVMS says "If the value of the name_index item is zero, then this parameters element indicates a formal parameter with no name."[1].
Shouldn't this case be already handled by the reflect impl?
Wouldn't it be also possible to just emit the attribute *with* names when it contains a mandated parameter? This would solve the problem with minimal changes as far as I can tell (with the downside of slightly increased class file sizes in such cases).

What would be the next steps here? Is my linked solution feasible?
