I think this is something we can work on or have changed. I only
checked the output of apt-cache. I think apt-cache however, is the
most common case for user who want to know about a package, but

requesting binNMUs requires access to wanna-build, AFAIK. Humble
ubuntu developers do not have access to that, just uploads. We can
talk about uploading policy. I ask to be corrected if I'm wrong on
this point.

It is quite similar to what debian calls a binary NMU, but developers
do not need wanna-build access to that. Instead, they upload a new
.dsc and .diff.gz, which gets accepted by katie as new package upload.

These kind of uploads are necessary during transitions, e.g. when a
package has been built against an older library but needs to be
rebuilt with an newer one.
