Comment 1 for bug 2052556

I checked this case confirming all you stated in the removal request.
LGTM

Furthermore the use-case of this explains why it might have been abandoned.
It is a less common (except in Japan) cd-rom book type.
And cd-roms have gotten way more rare these days right :-)
This does not remove all ability to access those.

There are eblook and a few go bindings left. But TBH, those just as much depend on an never changed library from src:eb. So there might be more cleanup needed down the road, yet OTOH no need to take things away if not being a problem.
But here blocking ruby 3.2 I think it is justifiable.

Removing packages from noble:
 ruby-eb 2.6-4build2 in noble
  ruby-eb 2.6-4build2 in noble amd64
  ruby-eb 2.6-4build2 in noble arm64
  ruby-eb 2.6-4build2 in noble armhf
  ruby-eb 2.6-4build2 in noble ppc64el
  ruby-eb 2.6-4build2 in noble riscv64
  ruby-eb 2.6-4build2 in noble s390x
Comment: not compatible with ruby 3.2 (LP: #2052556)
