This is refactoring, and not a fix. We don't need to have this
backported.

On the actual change, it's fine. But I do find myself thinking most of
the similar functions on the encoder->compute_config() path should 1) be
all named _compute_config, and 2) have the same parameter set as
encoder->compute_config(), needed or not. Because often you are going to
need something later, and then you end up having to plumb them all the
way the stack to the destination. It's just unnecessary to keep removing
and adding the parameters in the _compute_config() path. (And similarly
for many other encoder hooks.)

BR,
Jani.
