Remove Package from Gnome Meta-Package

[Lee Thompson <lee.p.thomp@gmail.com>]

Hi All,

Is there an analogue in Guix for NixOS's `excludePackage`? Under NixOS I
had something like the following in my system config:
> environment.gnome.excludePackages = with pkgs.gnome; [
>     cheese
>     epiphany
>     gnome-music
>   ];
Which allowed me to use a mostly OOTB Gnome install minus some packages
I really don't care about. I've seen some old 2018–2019 posts describing
ways in Guix to make a custom Gnome package minus the bits I don't want,
but I've had no luck so far with this.

I was really hoping there'd be a canonical, obvious and modern way of
achieving this, and if there is in the manual I've had no luck finding
it. Obviously this isn't a deal-breaker for me using Guix, but I think
it would be neat to have.

Any assistance appreciated.
