Re: [csswg-drafts] [css-fonts] Investigate using will-change: content to decide whether to use incremental font downloading (#6485)

> maybe you want to do less fine-grained incremental downloads?

Ah. With the old `patch-subset` approach, the client provided a list of 

- what it could render
- what it wanted to render

and the server computed a patch for _exactly that._ But this was a cache-buster, required a special server, and was a potential privacy leak.

With the current approach, the initial font contains tables of (urls to) patches, along with what is in each one. The client doesn't communicate with a server except to request some patch files. Of course the client can request patches for more than it currently needs; and as the patches are pre-computed (and thus, the same for everyone, and cacheable) they tend to not be very fine grained.

But still, it could be a useful hint for the client.
