Comment 3 for bug 1937922

"regression-update" is a tag for SRUs, not appropriate here.

Otherwise, nothing in this bug report has flagged it to the attention of the ubuntu-archive team, who are the only people that can add packages to the i386 whitelist. The general process we've been using is to ask folks on #ubuntu-release, but if you're going to file a bug about the i386 whitelist, please subscribe ubuntu-archive.

Do we need gtk4 explicitly added to the whitelist, or will something else that's currently built on i386 in the archive be using gtk4 in the impish release? (For reference, gtk+3.0 is not manually whitelisted for i386.)
