No.  I know of several applications which leverage exactly the behavior
you object to (which is common to *all* indexes).  For instance, I often
add a PythonScript at the root of the site (or in the 'custom' folder)
which uses business logic to compute the value to be indexed.

It should be trivial to write an acquistion-stripping plugin index, and
use that instead of the default indices.
