No.  Packages are records (the things created by calling (package=20
...), and upon which you can call (package-name ...) etc.).

git:out is the default output of the git package, but git:out or=20
git:send-email aren't packages in themselves:

$ guix repl
scheme@(guix-user)> ,use (gnu packages)
scheme@(guix-user)> (specification->package "git")
$1 =3D #<package git@2.28.0 gnu/packages/version-control.scm:157=20
790e385bd6e0>
scheme@(guix-user)> (specification->package+output "git")
$2 =3D #<package git@2.28.0 gnu/packages/version-control.scm:157=20
790e385bd6e0>
$3 =3D "out"
scheme@(guix-user)> (specification->package+output=20
"git:send-email")
$4 =3D #<package git@2.28.0 gnu/packages/version-control.scm:157=20
790e385bd6e0>
$5 =3D "send-email"

In all three cases, the package record is identical, since there's=20
only one =E2=80=98git=E2=80=99 package record.  Your selected output is sim=
ply=20
returned as a string.

Kind regards,
