Re: [PATCH v5 7/8] fetch-pack: put shallow info in output parameter

Brandon Williams [off-list ref] writes:

Expand the transport fetch method signature, by adding an output
parameter, to allow transports to return information about the refs they
have fetched.  Then communicate shallow status information through this
mechanism instead of by modifying the input list of refs.

Makes sense.  Would this mechanism also allow us to be more explicit
about the "tag following"?
