We do this in HTTP already to give the CPU some exercise while the disk is heavily spinning (or flashing?) to store the data avoiding the need to reread the entire file again later on to calculate the hashes – which happens outside of the eyes of progress reporting, so you might ended up with a bunch of https workers 'stuck' at 100% while they were busy calculating hashes. This is a bummer for everyone using apt as a connection speedtest as the https method works slower now (not really, it just isn't reporting done too early anymore).
