The problem with this is that the parser needs to decide where the subscript is
placed on way or the other.

The two choice that immediately come two mind are
  left ( a over b _ 2 right ) newline
  left ( a over b "" _ 2 right ) newline 
And it becomes worse if the same idea is applied to left subscripts as (and it
should be for sake of common overall behavior)
  left ( a over b _ lsub right ) newline
  left ( a over b "" _ lsub right ) newline 

There is no way a mere parser can decide what the users intend was when writing 
it. 

Also such a change will be incompatible with existing documents that might have
such constructs in use. You can't just have the formula
  left ( a over b right ) _2 newline
look differently from one version to another. 
Currently the "2" is rendered at the bottom of the right brace where according
to your proposal it should be rendered like
  left ( a over b right ) {}_2 newline
Thus there would be import and export filter required as well.

Maybe(!) it is possible to introduce some special rules to handle the case
better but a simple rule with no exception is usually preferable to more more
complex rules that have exception.

Overall: No, this is not going to be changed.
Especially not since there is a good concept that makes it clear to the parser
and reader(!) which way the user wants the formula to be rendered. It is the
very same construct that can also be used in TeX. 
And that is already almost what you did. The expected way to do this is using
empty groups. E.g:
  P(AB |{}_0)
