[SRU] Is there a process to have universe sources promoted to main in stable series?

[Sebastien Bacher]

Hey there,

That's a question probably for the SRU team.

I've recently uploaded webp-pixbuf-loader as a new package to 22.04 (SRU 
https://launchpad.net/bugs/1993789). The goal is to enable webp support 
on the desktop in the LTS. The package got promoted to main in Kinetic.
I would like to know if there is a formal process to ask for promotion 
in a stable serie?
The intend is to have the package pulled it by our default image viewer 
(eog), so that would be a SRU to eog adding a depends or recommends on 
webp-pixbuf-loader. Can I go ahead with the SRU or should I get input 
from the MIR team first?

Also for webp-pixbuf-loader the version in 22.04 is the same than the 
one that got reviewed and promoted by the MIR team, but we have another 
similar need for webkitgtk where we would like to build using 
libwpe/wpebackend-fdo but in this case the version in 22.04 is older 
than the one that got promoted in Kinetic, would that change the answer?

Thanks,
Sebastien Bacher
