That sounds like it will introduce silent breakage afterwards,
when xkb-data switches from -2 to -3 in its directory name.

I’d rather suggest that the “active” flavour of xkb-data
installs a symlink farm in /usr/share/X11/xkb/** and leaves
the latter as directories and that the thing that does the
X server configuration look in that directory so add-on xkb
layouts (I have one, too!) continue to work.

That is:

- revert the dir_to_symlink
- execute_after_dh_install needs to remove the symlink
  and add a symlink farm (if Debian only ships the one
  version, otherwise it would need alternatives)
