Since T330797 we do not use Phabricator Differential anymore for code review.
Since T191182 we do not host any repositories canonically anymore in Phabricator Diffusion - all repositories are mirrored into Diffusion from another place (Gerrit, GitHub, GitLab, etc) where code development actually takes place outside of Phabricator.
Clicking on the "Clone" button in a Diffusion repository, it makes sense not encourage folks to clone code repositories from Phabricator Diffusion but instead from the canonical code repository location: That would allow developers to do developer stuff (proposing changes via pushing custom branches etc) on their journey into a bright development contribution future.

Implementing this would also hide/fix {T347408} and {T347476} on the user side (though not really {T244907} on the management side).
It would still be possible to clone from Diffusion (needed until non-public {T213246} gets resolved) - the repository URIs provided by Diffusion itself would just not be advertised anymore via the "Clone" button in Diffusion's repository web view.
Wondering whether this should go along with some `diffusion.disallow-cloning-observed-repositories` setting or if my argumentation is... convincing™.
