Adaptation of hooks to the new release of LaTeX

[pablgonz]

Description

Just as a report and since the new LaTeX release is coming soon, maybe you should adapt this (hooks) a little bit.

Add info or delete as appropriate:

• Relevant for XeTeX
• Relevant for LuaTeX

Minimal example demonstrating the issue

\documentclass{article}
\usepackage{unicode-math}
\begin{document}
\[
  a = b
\]
\end{document}

Just as a further data point: Compiling the same MWE with \documentclass{scrartcl} yields a full 28 of those warnings.

XeTeX does not produce these warnings. Looking at the log, it looks like the bug is actually produced by lualatex-math. I'm going to report an issue there instead.
