Missing iotop in Aurora: Which upstream should I file a request with (ublue base image, Kionote, etc.)?

If I want to recommend a package that isn’t included in the image I’m using (in this case, Aurora), should I submit the request upstream to Kinoite/Silverblue, to Ublue, or to Aurora specifically?

For example, I noticed that iotop isn’t available in Aurora. Since it’s a small command-line tool, I thought it might make sense to include it in the base image, but I’m not sure which base image I should submit the request to.

Thanks!
