I’m reluctant to marking things like Chromium or OpenJDK as tunable
because they take ages to build: it’s more work for ci.guix (which
builds a few tuned variants of each tunable package), and possibly leads
to local recompilations for users when substitutes for their
micro-architecture are unavailable.
It’s also not immediately obvious to me why these two packages as well
as zlib would benefit from micro-architecture-specific optimizations.
Thoughts?
