This one technically isn't stable yet, despite being used at Meta ("Stage 2.5"). If anything I'd remove the unprefixed one and keep the unstable one. You can move the alias to the wrapper module in Meta's repo.

should the main React package be exporting this as unstable_SuspenseList as well then?

i'll follow up with a separate PR for SuspenseList changes – if i remove just the SuspenseList export here without other changes we get CI failures
