I see, thanks for bringing my attention to the fact that greetd provides
'-l' itself.  It seems it could be awkard to honor the default user
shell and have a default '-l' added to it, which may or may not be
supported (I guess most shells do, but...)

Murilo, what do you think?  Can we close this, preserving the fully
declarative status quo?
