Thanks for doing this. Hope it isn't too late, but I would like to suggest that protocol 5 support fast compression by default. We normally pickle objects so that they can be transported (saved to a file or sent over a socket). Transport costs (reading and writing a file or socket) are generally proportional to size, so compression is likely to be a net win (much as it was for header compression in HTTP/2). The PEP lists compression as a possible a refinement only for large objects, but I expect is will be a win for most pickles to compress them in their entirety.
