Well, we might come up with some solution but that won’t be soon. Our unstable branch is mostly on pair with Arch but people will use more our stable branch, on which we even have 5.24 plasma series in our overlay. So if we ship debug symbols we have to have a similar approach as we have with our current binary repos to have debug packages per branch matching our packages.
On a site-note: for ARM we have blacklisted all debug packages as ARM is shipping them on the regular mirrors, which will kick out most of our own mirrors if we would add those large packages.
