The thing is, that field is ALWAYS maxed out whenever anyone hands you

No.

It's the music industry that wants their *songs* to play as loudly as
possible, so they use dynamic compression to be able to make them as
loud as possible on CD.

You would never *want* to turn *up* the gain on these files, since it
will make the already-existing clipping even worse, but you can do it.

Thus altering dynamic range even further, or living with massive distortion,
the latter of which I'd hope most products would not consider as an option.

No, dynamic range is not altered at all.

The massive distortion can be undone. MP3 doesn't really have a noise
ceiling or floor like PCM does. The signal peaks don't actually get
clipped in the MP3 itself... just in the playback. So this "clipping"
distortion can be fixed by just reducing the gain of the MP3.
