It is, though I’m not sure how long it’s been default for. (This page says the default set of extensions is GHC2021, which includes NumericUnderscores. But it doesn’t say how long that’s been the default. Also, caveat that there are other Haskell compilers than GHC, microhs is the one I hear most about these days, which support different language extensions and idk about them.)
