Yes I know libgccjit0 is dynamically linked to it, so I don't intend to
keep out libgccjit0. Instead I intend to keep out some of the
dependencies of libgccjit0, specifically the following:
- libgcc-12-dev
- binutils
- libc6-dev (>= 2.23-1~)
I have just deliberately broken the dependencies and tested such an
emacs-nox installation. It seems to work as I expected:

emacs-nox is already the newest version (1:28.2+1-10).
You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
libgccjit0 : Depends: libgcc-12-dev but it is not going to be installed
Depends: binutils but it is not going to be installed
Depends: libc6-dev (>= 2.23-1~) but it is not going to
be installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages
(or specify a solution).

So IMO in libgccjit0 demoting those Depends: to Recommends: should work.
