best practise between git-fetch vs url-fetch?

[zimoun]

Dear,

Based on these 2 messages [1,2], what is the consensus between
git-fetch and url-fetch?

Pushing to SWH when linting appears to me winning the pros/cons.  Even
if SWH should eventually fetch http://guix.gnu.org/sources.json soon.
And the other big pros from my point of view is the content-addressed
Git references.

Well, does it make sense to state on a recommended method?


All the best,
simon
