This PR is extracted from #10927. It targets to current
main
.In another PR, I plan to re-introduce #10927 behind a flag (tentatively named as
BABEL_8_PRESET_OPTION_CHECK
) like we did in #11172, so it is non-breaking change (not if you randomly assignBABEL_8_*
env in your CI) and we can merge without holding off for a long while.
