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.

I think handling formulae files is always nicer than doing Formula.all and evaluating every formula, whether needed or not.

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?
