Further, we could have a "quirk" setting in the REST framework that allows weak etags to match in an If-Match header for specific endpoints.

There's been 700 cases when the If-Match was not supplied over the last month and only 2 user agents:

1. https://en.wikipedia.org/wiki/User:Jackmcbarn/editProtectedHelper - a user script. I will reach out to the maintainer
2. And, surprisingly, still VE https://logstash.wikimedia.org/goto/4b751b3fbf5de1044bd4255c693fc724

So let me see if I'm getting this right: VE gets HTML via Varnish and RESTbase. It's getting an ETag generated by RESTbase, and "weakened" by Varnish.

On Slack, @Arlolra pointed out that it may be Varnish adding the W/ prefix to "weaken" the etag. Per the varnish docs, this might indeed be the case: https://varnish-cache.org/docs/6.0/users-guide/compression.html

The issue originates in I5edfa8aa54dedaec418579bbef37aa040170d09b, which sais: ETag harmonisation Add custom weak ETag to page requests in the format used by RESTBase.

The RESTBase stashing mechanism also allows *lookup* by TID if i understand correctly, since you might have multiple parses of the same title/revision but at different timestamps. Maybe that's not actually required, and just keeping a single "latest parse" is sufficient. But if you wanted to lookup by TID you'd need to add it to ParserOptions as well, since that is used as the key for the <ParserOptions,ParserOutput> datastore implemented by ParserCache. (You'd might also want to tweak the cache lifetime mechanisms.)

But, once Parsoid is integrated into core and with ParserCache, and when HTML stashing is implemented for VE (similar to how it is done in RESTBase), the etag will come from this stashed entry.
