You're drawing some TikZ pictures lately? ;-)

I'm not familiar with TikZ, but I had a brief look at the manual and
indeed, using the scope environment without options is pretty pointless.

Keep in mind that if you want to use in-buffer completion when you're
inside the brackets, you need `(TeX-arg-key-val key=vals)' in the hook,
so I think the best would be if you could see if you achieve what you're
looking after with `LaTeX-env-args' -- but I think that wouldn't work
because of the (save-excursion ...) it uses?

See above.  Patching `ConTeXt-insert-environment' seems reasonable to
me.
