As discussed on gentoo-dev: This default doesn't actually solve the stated problem, and setting it in a high-level profile causes new ones for users who want it disabled. The obvious solution to revert to the status quo is to set USE="-zstd", but that has the dangerous side-effect of overriding IUSE defaults in packages where they are important. For example, sys-apps/kmod uses +zstd to ensure that your kernel will boot if you choose zstd compression for modules; helpful, because there's no other way for the package manager to track that dependency. There are other more appropriate places for USE=zstd: * In a profile that the user has to choose, like the desktop profile. * In the packages themselves, as IUSE defaults. * Nowhere :) All Gentoo users know how to set USE=zstd if they want zstd support. You learn this before you even boot into your first Gentoo install.
If you're looking for consensus I've been following the threads on gentoo-dev and would agree with this change to the profile. There are other, more sensible, places to put this as a default directly in the packages where it's important.
