Unless I see attested usage demonstrating otherwise, I assume that
superscript 2, 3, 4 are used in Tamil in particular since it does not
have the complete series of five consonants for each point of
articulation that the other Indic scripts have.
Since Tamil doesn't have consonant clusters, the only issues involved in
using superscript digits is working out what the interaction with matras
is in encoding and rendering. If you were to suggest that Devanagari or
Bengali or Kannada consonants can be modified with superscript digits,
that would raise lots of questions about how it all works. (A sequence <
ka, virama, sup_two, ta > or < ka, virama, ta, sup_two > displays how?)
So, IMO until we are shown what is actually used, we should *not* assume
that this should be generalized across Indic scripts.

Why don't you submit a document showing such samples.
