I suspect 128MB was chosen as a "big number" that is large enough for any .uf2 file that could be sent for any possible (now and future?) memory capacity.
A 32MB binary would have a 64MB .uf2. The drive would have to appear be larger than that as some space would show as used already. So 128MB would be the next power of two up.
I don't think a PC would have a lower size limit for recognising a drive. After all, a floppy drive could be anything from 160KB upwards and they are recognised.
I have a 8MB SD card somewhere that works in a Pi.
