(Copying from Twitter in case it helps to have approval here too)

Something like this is definitely preferable & reduces the overall bundle, thanks for doing it! As Jovi mentioned, you could save a quite a few bytes by just setting up the subscription stuff manually and not trying to use this API specifically, but if you want general parity w/ the React impl, there's nothing wrong with this.

As mentioned in the other PR, I'll poke around with creating a separate entrypoint in Preact itself but not sure when I'll have time or if that'll go anywhere.

this is pretty cool
