This avoids pulling in 16 and 17. But I haven't actually verified if yarn or yarn deduplicate are that aggressive so I'll catch up on that.

These aren't released yet. If npm and yarn don't complain on a fresh install we should get this in as well. @types/react@17 is already proposed in DefinitelyTyped/DefinitelyTyped#48971

This feels a bit awkward as a direct dependency but should "just work" in practice. More details why this is technically wrong can be found in facebook/react#20099.

On a related note, did you have a look at the React 17 issue in #23215? I could only find one solution, but I'm not 💯% happy with it. Maybe you have some better ideas. |
I'll take a look. Though I would've preferred if the first advise is to not use React 17 yet instead of some timer workarounds. They likely break in more subtle ways. |

I'll investigate #23215 first. Hopefully we can write a test that fails with 17 so we can rely on our nightly tests. |
Allows React 17 as a peer dependency in all packages.
Installing it in the main repo needs a bit more upstream/downstream work. Since we test the
nextrelease channel daily, it should be fairly safe. Most of the compat issues have already been resolved before 17 was released.Closes #23306
Test plan
2v2 does not allow installs from urls i.e. can't be tested with csb deploys)
