Re inline requires:

is [the fbjs plugin] the same as the transform flag in Metro config?

Yes, it is: https://github.com/facebook/metro/blob/5c6897eba2ac6d5524f554f11f5baaa5d3156e43/packages/metro-transform-worker/src/index.js#L325

[Nicola Corti (cortinico)]

coming up: align-deps + rnx-kit conversation (#1863)

I've missed this as I haven't got the meeting invite. Anything relevant?
