PQ Universal was once listed as a film developer in older Ilford literature, it still is for Ilford Ortho Plus. I've used it commercially at 1+19 where I've wanted a slightly higher contrast and 1+29 for normal working.

The quality from PQ Universal is excellent good fine grain, excellent tonality and it's cleaner working than D76/ID-11, there's no reason it can't be used. Having said that with high dilutions the freshness of the concentrate is important.
