Something like a list of named sequences would be useful as a reference
of *known* base+mark combinations likely to occur in text, and as such
would be useful for font developers employing many-to-one glyph
substitution ('ligation') to provide precomposed glyphs for such
sequences. But dynamic mark positioning using anchors is a much more
flexible approach, and has the benefit of being able to support
arbitrary combinations of bases and marks, such that one doesn't need to
know what sequences are more or less likely to occur in text.
