In that case the issue is not a significant one. But if there were a
real division of opinion in WG2, that would be a different matter.

It might be inconsistent with the Unicode model, but that doesn't imply
complete chaos. Unicode already includes large sets of precomposed
characters and presentation forms, including Arabic presentation forms
which completely break the Unicode Arabic encoding model. Nevertheless,
Unicode lives with these successfully by giving them canonical
decompositions, and where Unicode wishes to effectively deprecate the
characters they are included in the composition exceptions table. My
suggestion was simply that Unicode could do the same with these
precomposed Tibetan forms (obviously allocating them to somewhere in a
higher plane), and the level of chaos would be minimised especially if
Unicode automatically normalised such text before processing, thereby
converting these precomposed forms to their regular Unicode representation.

If this is in fact not necessary, then no action is necessary.
