I guess you haven’t tried AMD’s composable kernel on Gentoo, or qtwebkit. I have a special env for the former called half-the-threads because it eats 2.5GB per thread. I removed the latter as soon as I was able to. I even add 32GB (half my RAM) of ZRAM for CK, and the Gentoo ebuild has a check for enough RAM per thread that stops the build if unmet, it wasn’t there before and I’ve had my system lock up because of OOM which OOMD wasn’t quick enough to catch.

All of this is to say that, it does have a potential impact on flash, if you rebuild often, which tends to happen on Gentoo.
