80% of pull commands are going to be for content specs. I propose making it the default, and a switch needed for other artifacts. As a design principle we should have a sane (majority case) default for everything.
We should make -c the default for all commands.
Fixed in 0.22.0. With the new client I have made -c the default command for all commands.
Verified in cspclient-0.23.2-1.
