Thanks!  I didn’t see this before writing my other message, but it
explains why the comments and code don’t match.

Maybe the GDM folks expect that we write a custom “.desktop” file that
runs a custom script that checks for “~/.xsession” and runs it.  It
could use “TryExec” to figure out if “~/.xsession” exists, and offer it
to the user (in the session selector) in that case.  To be concrete, we
would create a “user.desktop” session file with the following contents.

    [Desktop Entry]
    Name=User Session
    Comment=Start a user-defined session

Here, “run-user-xsession” and “xsession-exists-p” are custom scripts
that we would write.  If this file were somewhere that GDM knows about
(e.g., “/run/current-system/profile/share/xsessions”), it should work.
