I think so yes. Replacing gtk_hbox_new/gtk_vbox_new with gtk_box_new is
one that looks trivial to do. I feel replacing gtk_container_add with
gtk_box_pack_start/gtk_grid_attach is probably another fairly easy
hack.

With https://gerrit.libreoffice.org/c/core/+/108050 I'll drop the never
completed GtkSalPrinter which drops a bunch of stuff that
-DGDK_DISABLE_DEPRECATED -DGTK_DISABLE_DEPRECATED flags as deprecated
which brings the warnings/errors there down to manageable levels.
