Well, this is an improvement compared to the previous behaviour. :-)
See 0074844366381e3056d09492b8b437836c7adb61:

--8<---------------cut here---------------start------------->8---
pack: Provide a meaningful "repository name" for Docker.

Previously, images produced by 'guix pack -f docker' would always show
up as "profile" in the output of 'docker images'.  With this change,
'docker images' shows a name constructed from the packages found in the
image--e.g., "bash-coreutils-grep-sed".
--8<---------------cut here---------------end--------------->8---

And one thing discussed at the time of this change was that the rename
for a more meaningful name could append on the Docker side.

That’s said…

…yes, I agree.  It could be nice to be able to directly name the image.
However, this would mean that the produced Docker pack would not be
bit-to-bit reproducible considering the same manifest.  Other said, the
bit-to-bit reproducibility would require three inputs: the channels.scm
file describing the revision of Guix (and potentially other channels),
the manifest.scm file describing the packages and also the name provided
at Docker pack build-time.
