I agree that the 'gc' strategy no longer serves users as a good default. For those that want foreground commands to trigger maintenance (detached on Unix, and as a blocking child on Windows) the 'geometric' strategy is a good one.

Instead of "configured by Scalar" I'd say instead "configured when initializing background maintenance with 'git maintenance start'" which is how how Scalar sets this up indirectly.

Users could still opt-in to 'geometric' in the background, but it would cause difficulties for the largest of repos that rely on the 'incremental' strategy's limit of the amount of data processed.

Should this include some kind of documentation update in Documentation/config/maintenance.adoc?
