However, looking at the Pentium Overdrive pinout the extra row of pins doesn’t seem to be at all essential. There is a number of extra power points and some signalling pins to support L1 cache coherency when using write-back. Nothing too much to worry about.

Uh... sure, if you say so.

Yeah, if I well remember from similar Intel manuals, no power/GND pins are marked as optional, quite the contrary

Though, given how it might be using low power (and maybe with some overdrive adaptor quirk), it might have worked this time
