The reason was that "auto" is way easier from a user perspective and not
expensive on the CPU.

The previously planned feature would have required to maintain a file
with a list of file formats and advised compression algorithms, reliably
detect file format (which is an non-trivial issue by itself) and then
still having an issue with file formats that might be compressed or not
internally.

You could find the discussion on borgbackup's github issue tracker.
