It's not a problem that we have them, but you would approximately never want to use them: - portability - compilers optimize standard functions (AFAIK), and isinf is one. - maybe nicer to use the type-generic variant one time someone had used isinff in a test which made stealing said test harder, so that's when I added it to the wishlist.
