Guix gc removing important packages?

[Andreas Enge]

I just did the following:
  guix package -d
  guix gc
to have only the current profile and its packages on my disk.
Then I wanted to delete one package:
  guix package -r texlive

This resulted in the following output:
The following package will be removed:
   texlive      2013    /gnu/store/in5hhsj3335k1mkdq15y855mya430c6v-texlive-2013

The following derivations will be built:

Is this normal? Should removing packages not be possible without an internet
connection? Does "guix gc" need to be modified to keep essential packages
registered?
