Pretty sure server push is being deprecated - current implementation is 'only half a feature', as clients lack the ability to tell the server what's already in cache.

In theory the client can cancel the response for a resource it's already got but by the time the response bytes reach the client it's really too late

Yeah and if the client volunteers the list of all it has in cache it would result in some massive requests and a kind of quasi-cookie.

I always found this feature interesting but weird.

Random thought. But isn't this a potential use for a bloom filter?

Yes bloom filters were a potential for Cache Digests, original prototype for Cache Digests used Golomb coded set as memory representation is smaller than Bloom filter

https://github.com/h2o/h2o/issues/421

But then Cache Digests moved onto Cuckoo Filters - https://github.com/httpwg/http-extensions/pull/413
