Regarding TypeScript, I think it's important to point out that we have a working PR in the TypeScript repository that we've been maintaining for about a year now. It's not so much special casing as being ahead of trunk. I still hope the TypeScript team will show interest eventually and we'll be able to streamline the development.

I meant special casing in the sense that this a conscious effort specifically targeted at Typescript support, as opposed to some generic design that would cater to a large class of projects.

Mind you, I understand that there are legitimate reasons to approach it this way now (e.g. technical limitations, differences in opinion wrt project governance, cost/benefit on long tail, etc). I'm mostly cautioning the unaware that one shouldn't necessarily expect that every package will work under yarn v2 (though an overwhelmingly large majority does work just fine).
