Yes, now it is accepted [1] and it becomes the format of the
'sources.json' file.

[1] https://forge.softwareheritage.org/D2025#65063


The patch set v2 supports the first discussion of the format (single
url); which is not relevant anymore.
The patch set attached in v3 [2] supports the array of URLs.

What I mean is: append %content-addressed-mirrors for each package in
the list of URLs.
