I don’t think it’s acceptable. Maybe works in pinch to get through a weekend but I would always replace it with a proper fitting. Plus if you damage the female threads or o-ring seat, you’ve made a much worse problem for yourself.

It's probably a commentary on the idea that the tapered male diameter is its max diameter(?), versus straight is throughout.

Consequently, a tapered male will fully screw into a straight female, albeit with gaps between the threads at the deep end of the socket.

Whereas a straight male will at most only screw the first few threads into a tapered female, leaving most of the male hanging out.

Tapered pipe threads are actually much larger than you’d expect given the nominal diameter. 1/4 inch tapered pipe threads have a maximum outer diameter of more than 1/2 inch and 18 threads per inch. They will sort of work with a 1/4 inch straight thread but not by fully screwing in.

It’s asking to rip the threads out of the fitting (and have done so when trying). One way you’ll get some seal first, the other you won’t.
