My understanding was that the \@kernel hooks should only be used

- for 'absolutely non-skippable' code
- by the kernel, i.e. latex.ltx directly

So by both criteria it's ruled out here: usage is by expl3 not 
latex.ltx, and the functionality here is nice not essential (i.e. if 
it's skipped, basic code doesn't break).
