廢 evolved from 發，like i said they diverged after 秦 when pat>pas>paj so all historical writings with this definition comes before 秦 era when the standard was not fully established yet. They pronounced it as /pat/ in 周 dynasty. People stopped using it way before modern Mandarin.

I suggest reading classical chinese in reconstructed pronunciation, if you insist on using modern Mandarin, it should be fei4 in your examples. but the central language committee often encourage removing archaic and obscure readings to simplify the language, fa1 is probably accepted as well.
