Okay. I don't understand the distinction between trunk and release
branch here, but I assume this must be sensible.

Indeed, it is a fairly gross kludge.
It would be nice if font-locking could somehow set up syntax-table
text properties to make this work correctly. However, I think the
syntax-table text property feature is not sophisticated enough for
handling LaTeX. You can only assign syntax-table text properties of
the form (SYNTAX-CODE . MATCHING-CHAR). It is probably necessary for
LaTeX to be able to do something of the form (SYNTAX-CODE
. MATCHING-STRING). For example, “\begin{xyz}” would need a
syntax-table text property that says it is matched by “\end{xyz}”.
Right now you can only specify single matching characters.
