Why doesn't React have slots?

Imo <ProfileCardRaw description={<p>A very cool person!</p>}/> (especially if there are more props/render props!) is a lot harder to read/parse than <ProfileCardRaw> <p slot="description">A very cool person!</p> </ProfileCardRaw> This is an opinion, other peoples opinions may differ.

perhaps, I think that's only really true if you have one or few props. when you have many, it's nicer to more quickly see slots imo. but for slots, I'd do this syntax:

(counter to an earlier point I made) I think the platform kinda messed up on the syntax of slots, and the above is way better than: <arbitrary-element slot="whatever"> additionally, many slots don't even need or want a host element (p in your example).

The problem you mentioned about knowing how it'll be used is a problem of the docs, not a problem of the syntax. Slots don't tell you how they'll be used any better than component props do, since all you see is a name and some magic syntax. Even a simple JSDoc comment over the prop definition works.
