And back to my original question - is a PR on https://github.com/openwrt/opkg-lede/ enough to get my suggestion done or do I need to do this somewhere else?
Whrn you get to openwrt/openwrt repo from wildly outdated pkgdata pages right above file listing there is a box showing branch 22.03, click and change to 24.10.
(and I see that there is a PR created 40 minutes ago which I assume means that you figured it out already)
That said, I doubt that your PR will get merged or even looked at because OpenWrt is on the way to switch to another package manager - apk, possibly already in the next release.
