With all the brains collected on this list, how hard would it be to
actually make one, to our own standards? Geez.

If you want a device that programs generic parts, not difficult.
But many manufacturers do not release the programming algorithms except
to companies that are in the business. I can just imagine the support
issues.
What parts do not have published programming algorithms? I you are buying your
own parts, just avoid chips or manufacturers that don't provide this
information.
To make a universal programmer, yes, getting the programming algorithms for
A wide range of chips and manufacturers is a problem, but the original
question was about 32 pin EPROM/FLASH. These all have published programming
algorithms since they are expected to be programmed in-circuit, so a
programmer for this type of chip is easily done.
Older GALs (Lattice at least) have a published programming algorithm.
Most newer CPLDs that I am aware of have a published programming algorithm
(for the same reason as above, they support in-circuit programming)
Many microcontrollers have published programming specs...
