I think "time only budget" vs "sector budget" is dependent on the
definition of fairness: do you want to be fair in the time that is
given to each cgroup or fair in total number of sectors transferred.
And the appropriate definition of fairness depends on how/where the IO
scheduler is used. ...

Just a general note: as Fabio already said, switching back to time budgets in BFQ would be (conceptually) straightforward.
However, we will never get fairness in bandwidth distribution if we work (only) in the time domain.
