Thanks Lukas and Utkarsh for the replies.
I've targeted those MIR reports to 22.04 now as you suggested. I'm
mentioning them for reference as I'm unsure if they would show up on
your standard query since the 'active serie' status is fix released and
by default launchpad buglists don't show past series unless specified.

Hey there,
That's a question probably for the SRU team.
The question if a new software feature can be enabled in a stable
series post feature freeze is probably a question for the SRU team,
indeed. But I don't think there's any formal process to it.
But this case also requires involvement of the MIR team, IMO.
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?
First, we (the MIR team) had a very similar case with fwupd ->
protobuf-c in the past, although that was for hardware enablement,
which might be a bit stronger case than enablement of a new software
feature:
https://bugs.launchpad.net/ubuntu/+source/protobuf-c/+bug/1956617
So retroactive promotion to "main" in stable series is possible and
has been done in the past, and we've been using the normal MIR process
to find consensus. The MIR and potentially security teams should
agree, which should be easy if the same version of a software is
already supported in another series. I'd suggest using the same MIR
bug, adding the required target series, to get formal agreement from
the MIR and security teams, before uploading any SRU pulling in the
new dependency.
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?
As outlined above, I'd suggest to use the same MIR bug that was used
for promotion in Kinetic, adding the required target series and asking
for MIR review/ACK from the corresponding teams, before uploading an
enablement SRU.
It might be harder, require some extra work or even not be possible at
all to get the older (currently unsupported) version of a software
promoted to main, depending on the MIR/security assessment.
Cheers,
Lukas
