[webkit-dev] Site isolation platform code

[Alex Christensen]

I found another place where the shape of platform-specific APIs does not lend itself to implementing site isolation.  See https://github.com/WebKit/WebKit/pull/38982 specifically the FIXME comments in the GTK and PlayStation code.  I’m pretty sure PlayStation will need an API change, and I’m not very familiar with the GTK API implementation and I’m not sure if it will need a change, but it definitely needs someone more familiar than I am to hook it up.  And the WPE code will probably need at least a double check.

This is probably not the last time I’ll be reaching out with such platform-specific assistance requests.  Are there individuals that would be good to reach out to on Slack for things like this?

A lot of changes are happening in this area right now with the adoption of Skia, and it would be great if it were done in a way that could support site isolation.
