For now: yes, it's more difficult to discover for sure. But users will
adjust over time as they get more familiar with git-refs(1), and from
thereon I think it will become significantly easier to discover that
subcommand.

git-refs(1) already hosts everything needed to handle references, so
from my point of view it is only natural to also provide an easy way to
read a single reference to complete the picture.
