I would say so.

It's truer to say that the Unicode standard is out of date. TUS ought
to define the correct orders, rather than leaving one to guess for
Myanmar script languages other than Burmese. By correct, I mean that
anything in a canonically inequivalent form is liable to be
misinterpreted. In some cases, the simplest exposition will yields
sequences that are not in canonical form; I think 'Keep it simple,
stupid' should be the guiding principle for comprehensive definitions.

The order <ASAT, DOT BELOW> for Burmese appears to depend on what can
be inserted between them in other languages.
