@martincostello, can we make changes for each package separately? It will be much easier to review.

It will be great to both enable AoT and switcc to the new build pipeline.
You can find example here for a brand new project, but changes for the exisiting one should be similar #1507

[martincostello]

Can do, though I didn't think this was a particularly big/contentious PR so that's why I didn't do them separately (like I did for #1544).

I'd prefer to get #1540 get merged before I do that as otherwise I have to do branch gymnastics locally to validate the changes I'm making.
