There's not usually a single fragment of the ES spec to which a given proposal corresponds - most proposals touch parts across many sections.

Yes, I understand that. What my suggestion would cause is that all the fragment IDs for all parts of the proposal would redirect to the exact same fragment IDs in the current ES draft.

For example, https://tc39.es/proposal-class-fields/#prod-PrivateIdentifier would redirect to https://tc39.es/ecma262/#prod-PrivateIdentifier — or preferably, to https://tc39.es/ecma262/multipage/ecmascript-language-lexical-grammar.html#prod-PrivateIdentifier.

This would work because y’all seem to have a policy/practice/convention of all id attributes in the proposal source being preserved as-is when you merge them into the ES spec source.

(I’ve edited/updated the issue description to include the info from this comment.)

personally, I get a lot of value from the diff view on the proposal pages - I wouldn't want to see that go away. for example, if someone links me to the PrivateIdentifier section that you've been using as an example, I really like seeing what additions were made by the proposal. I think it's important to keep that functionality around even after a proposal lands.

It's true that the single-page version is canonical, but I disagree strongly with the claim that this implies everyone ought to link to it. The two documents have the same content, by construction, and the multi-page one is friendlier for many users.

In places such as https://github.com/w3c/browser-specs/blob/master/specs.json#L67 and https://github.com/tobie/specref/blob/main/refs/biblio.json#L1098, we’re now very intentionally referencing the multipage ES spec rather than the single-page.

And for MDN, we’re following a policy of only linking to the multipage version — just as for links to the HTML spec, we have a policy of only linking to the similar multipage version of that.

In the cases of both specs, the primary reason for linking to the multipage versions is better user experience:

• The published single-page HTML spec is 11MB, and loads slowly even for users with a relatively high-bandwidth connection — let alone for users on lower-bandwidth connections. The multipage sections load much more quickly.

• The published single-page ES spec is 5.8MB but has a similar issue with not loading nearly as quickly for users as the multipage sections do.

I suspect you’d likely not have great success getting third-party sites to avoid linking to the multipage version.

@sideshowbarker thats not my experience outside of chrome, which has a particularly poor experience for the single-page version.
