I just tried those changes and PVRGeoPOD disappeared from the Export menu, just as though it was no longer enabled in prefs. I went into prefs and it was enabled, but if I disabled it, Blender then wouldn’t allow me to reenabled it. Blender looks to be detecting a problem with the script even without running it.
Sorted. I had a tab in a file that mostly used spaces. Yes, all looks to work now with those changes made. I haven’t tried any of my models that involve bone animations yet, but everything else looks ok. One of my materials came out strangely, but that may be that I messed something up in blender.
I’ve updated the file linked above with the working version.
