I see, this is indeed something I hadn't considered.

However, your documentation indicates that this is officially supported:
https://doc.qt.io/qt-5/qtwebengine-platform-notes.html#using-earlier-qt-versions-to-build-qt-webengine

"Building Qt WebEngine with earlier Qt versions (down to the last LTS
version) is supported. It means that Qt WebEngine 5.15 can be built with
Qt 5.12.x, Qt 5.14.x, and Qt 5.15."

(Sure, it says "can be built" and not "was tested" or "actually works",
though that's kind of implied there)

Does it, though? Only because a 5.15.3 tag exists I don't think it's
implied that it's officially supported to combine 5.15.3 and 5.15.2
tags.

If the policy is "only matching patch releases are officially
compatible" or "only whatever is integrated in qt5.git is guaranteed to
be compatible" that's fine (except that it's contrary to the docs
above), but then a new 5.15.3 tag doesn't change anything about that.

I don't see how pushing a tag would do any harm, or give any indication
of a stronger "guarantee" than what already exists.
