Sure, just need to tweak the action a bit, though it... is... pretty... slow... (slower than a build+test run on linux) and I'm not sure it is all that beneficial, but I'm happy to be convinced (in any case, it's much faster than a full benchmark run)

[ekoops]

Yeah, not an issue. We can take it as is and introduce the check later if need arises
