pkg 2.7.3: "pkg update -rFreeBSD-base" still reports "No repositories are enabled." instead of just updating FreeBSD-base when FreeBSD-base is "enabled: no"

From my https://github.com/freebsd/pkg/issues/2643 submittal:

# pkg update -rFreeBSD-base
No repositories are enabled.

# pkg-static update -rFreeBSD-base
No repositories are enabled.


For reference:

# pkg -v
2.7.3

# pkg-static -v
2.7.3

# head /etc/pkg/FreeBSD.conf /usr/local/etc/pkg/repos/FreeBSD.conf
==> /etc/pkg/FreeBSD.conf <==
#
# To disable a repository, instead of modifying or removing this file,
# create or edit /usr/local/etc/pkg/repos/FreeBSD.conf, e.g.:
#
#   mkdir -p /usr/local/etc/pkg/repos
#   echo "FreeBSD-ports: { enabled: no }" >>
/usr/local/etc/pkg/repos/FreeBSD.conf
#   echo "FreeBSD-ports-kmods: { enabled: no }" >>
/usr/local/etc/pkg/repos/FreeBSD.conf
#
# Note that the FreeBSD-base repository is disabled by default.
#

==> /usr/local/etc/pkg/repos/FreeBSD.conf <==
FreeBSD-base:        { enabled: no }
FreeBSD-ports:       { enabled: no }
FreeBSD-ports-kmods: { enabled: no }

PKG-UPDATE(8)

NAME
     pkg update – update the local catalogues of the enabled package
     repositories

SYNOPSIS
     pkg update [-fq] [-r reponame ...]

     pkg update [--{force,quiet}] [--repository reponame ...]

. . .

OPTIONS
     The following options are supported by pkg update:

. . .

     -r reponame, --repository reponame
            Download the catalogue for the named repository only.  This
option
            can be specified multiple times to update several repositories.

"enabled: no": configured for there being no defaultrepository.
