Yes, I concede this has parallels in the world of EPROMs where every manufacturer's version of (let's say, 2764) would offer its own fast-programming algorithm, for which the specific device AND manufacturer had to be selected in order for it to work.

The difference was that with EPROMs there was always a fall-back 'slow' algorithm which would work with any 2764, usually accessed by choosing 'Manufacturer: Generic'.

No such luck with these bipolar PROMs, unfortunately.
