I assume you mean (guix build utils), as changing (guix utils) should
not rebuild anything.

You might be able to alter (guix build-system gnu) without triggering a
world rebuild.  But I don't know how satisfactory e.g. a #:desktop-entry
would be.

There are other ways too (say a package property and profile hook),
depending on how urgently we need this feature.

In any case core-updates is long overdue, so the waiting time should not
be too long.
