Steven Edwards did tables. Eugene did them in a different format. Thompson did the same followed by Stiller. Bruce did his own format. Vincent did one although I don't know if he ever finished it. But, with all of that, they are all accessed in the same way, and they produce the same identical information for the same position. Therefore there is nothing "unique" in them that would make my version distinct from your version, other than the compression technique (if any) and the order of the pieces used to produce the Godel number. I see no problem with people sharing a good list of random numbers to see the Zobrist hashing algorithm, any more than I see any problem sharing tables, since the two kinds of data are identical in nature. Books are far different, however, and are a big sticking point in current rules.
