I adjusted things as proposed and pushed:

  b5e3701f1a environment: Avoid false positive on 'PS1' check.
  632e2f7ce1 environment: Simplify 'PS1' suggestion on '--check'.
  086df6ef21 system: Define default 'PS1' in /etc/bashrc rather than ~/.bashrc.
  2127e56bd8 system, home: Factorize default '.bashrc'.

Thanks!
