Hello Moshe,
thanks for your feature request.

I am under the impression that your need is a bit unusual.
The reason is that apt-listbugs is most useful (I think), when using
Debian testing or unstable and upgrading reasonably often.
In this scenario, it is quite uncommon to see a very long list of RC
bugs during one upgrade session...

However, I see that you are using Debian testing, but apparently you do
not upgrade very often (your system still thinks that bullseye ==
testing ...).
Oh, and I also see that you configured apt-listbugs to also show
important bugs, along with RC bugs.
These two points might explain the bigger number of bugs that you
encounter.

I don't know whether I will consider implementing a paging option for
apt-listbugs.
A naive implementation could be feasible without too much hassle, but
it would be too tied to specific tool choices (for instance, it could
be written to forcibly use the "less" pager, but, what if a user has or
prefers another pager?).
Maybe a more general solution should be sought.
Perhaps the use of a helper Ruby library, such as [tty-pager]?
Unfortunately, it seems that this library is not (yet) included in
Debian. Would you be willing to file an RFP bug for this library
(or, better yet, to file an ITP bug and package it yourself)?
