Because it needs to connect to the running gpg-agent and fetch the
socket name.  Using gpgconf is easier.  Or the portable way:

  $ gpg-connect-agent '/datafile -' 'getinfo socket_name' /echo /bye
  /run/user/1000/gnupg/S.gpg-agent

(In a script I would suggest to replace "/bye" by "</dev/null".)

Already done:  Use "none" or "/dev/null" to -e-xtra or --browser socket.

The option name is in use for quite some time, thus we can't really
change it anymore.  Yes, an alias for the option would be possible but
then we need to restart the discussion on whether "restricted" is a good
term :-(.  I hoped we had found a compromise by keeping the option name
but naming the socket file "S.gpg-agent.rstrd"
