They mentioned that they wrote their own assembly functions for some floating point routines, like sqrtf. Is the ARM floating point unit fast enough that the quake fast inverse square root [1] isn't required?

What an excellent example of designing for the medium instead of trying to make the medium do something it's not good at! Your whole approach shows a real love, like a delicate respectfulness, that I think characterises early games and is less apparent as the systems get better (though I am sure it is still there).

Yes, it reminds me a lot of the ports between 8-bit computers in the 80s, and also console ports pre-Playstation.
