That's fine for engineering, which provides its own scope for what "matters." But for a theoretical physicist, the issue is that there are domains in which general relativity and quantum field theory simply diverge and so cannot possibly both "work."
Yes, it seems overly broad to me. OTOH it may have been a useful intervention in the philosophy of science at the time because foundationalism and nihilistic disunity-ish were both still considered credible by many.

Interesting thread. As an theoretical astrophysics person, who has special interest in exploring observational implications of physical models, "it works" type engineering approach feels just deeply dissatisfactory. ...

Well, “rationalism” is approximately “using patterns of thought that are effective in physics in other places where they don’t work well.” So one *should* use those ways of thinking in physics, and if someone doesn’t, they may be making a mistake.
