Considering that parallell base backups would be io-bound (or

That's not actually true. Backups at the moment are CPU-bound, and
running them in parallel is one way to make them closer to I/O-bound,
which is what they *should* be.
That's a different kind of "parallel". We're talking about taking
multiple backups in parallel, each using one process, and you're talking
about taking one backup using multiple parallel processes or threads.
