Can we have this function exposed as part of the public API to align with getEffectiveTypeParameterDeclarations?

Hm. We should have these notes as jsdoc for lots of things now. Something for a separate PR though.

Only the first type parameter in a list is constrained by the constraint. Can you add a test for that? That is, /** @template {number} T,U */ only constrains T.

That was done in #24600 for the reason that reusing a node would be bad -- maybe not necessary now?

The test jsdocTemplateTag3, added in #24600, will have fewer errors if this is changed, so it's already being tested.

I don't like applying the constraint to multiple parameters even if there's no implementation reason that it's easier.

A node needs to contain its children, but in
/** @template {number} T */,{number}was made a child ofTdespite not being contained in its range. Changed this so that{number}would be a child of the@templatenode which spans all the way to the end of the line.
