Is it a bug that core ships gawk as the default awk?

Is it intended that core ships gawk as the default awk, instead of the small and lightweight mawk as Ubuntu does? You can open a shell into any snap and check it.

$ awk --version
GNU Awk 4.1.3, API: 1.1 (GNU MPFR 3.1.4, GNU MP 6.1.0)

I prefer to set it back to mawk:

  mawk:
    plugin: nil
    override-build: |
      snapcraftctl build
      mkdir -p $SNAPCRAFT_PART_INSTALL/usr/bin/
      ln -s /usr/bin/mawk $SNAPCRAFT_PART_INSTALL/usr/bin/awk
$ awk --version
awk: not an option: --version
