This is most straightforward and IMHO correct way to start
whatever user wants.

No, you should not care about stuff happening in script in
`make-greetd-sway-greeter-command`. User session is started by
scripts within `make-greetd-user-session-command` and
`make-greetd-xdg-user-session-command`. Where user session command
is specified by `command`, `command-args` and `extra-env` in
`<greetd-user-session>`.
Most notable impact of this change, as noted in cover letter is
that user session now factored out. Now you are able to pass
instance of `<greetd-user-session>` to any properly defined
greeter, which are agreety, wlgreet and gtkgreet as of this
change.
I'm not RDE or guix home user, but I suppose that their entry
point should be an instance of `<greetd-user-session>` or
combination of greeter and `<greetd-user-session>`.

Technically, you may set `command`, `command-args` and `extra-env`
to sway, its required arguments and if necessary environment
variables of `<greetd-user-session>` instance, carefully
considering `xdg-env?` and `xdg-session-type`. But, as I mentioned
above, IMHO and from my experience, starting from
.bashrc/.profile/whatever from user home and editable by user is
more correct and straightforward.
