Yeah, so I had posted https://gcc.gnu.org/pipermail/gcc-patches/2023-November/636855.html for that but held off from committing it at the time as IMO there wasn't enough evidence to show that this helps in general (and the pass could in theory miss opportunities which would lead to regressions). But perhaps this is a good argument for going ahead with that change (of course it will need rebasing).
