As mentioned before: I'd love to see this be a temporary stop-gap while we add a DSL. I think this needs some pretty hefty amounts of comments until then explaining why these particular formulae need to be doing what they are doing here.

return true if @testing_formulae.any? { |f| NEW_INTEL_MACOS_MUST_BUILD_FORMULAE.include?(f.name) }
return true if @testing_formulae.any? { |f| f.formula.class.pour_bottle_only_if == :clt_installed }

Formula.all.any? do |formula|

can this instead use e.g. the relevant tap(s) instead of reading all formulae unconditionally here?

I can skip formulae not in the given tap, but Tap objects don't seem to have a nice way to recover the formulae they contain. They can give me the formulae files, but not sure handling those directly is nicer than this.

You probably need to pass eval_all here

Yep, will add it when I get around to updating the calls in homebrew/core

Was removing the !@all_supported intentional?

It's up here:
