After more analysis and comments from Dave about what will happen in
5.11/5.12 I think these can be forgotten. Plug in engines will just

I have a patch for this of sorts, its a little hacky though and maybe
not worth it in light of the new status of point 1.

I have done nothing on either of these yet. Id really like to see them

Done and applied.

Done and submitted.

Which means I guess that all is left for me is:
