Jeffrey,

we actually used to do this in GenBank (aka DDBJ/EMBL/GenBank), but we
don't anymore as no benefit is really derived from this, and
information is actually lost.

Having a poly_A tail is information in clearly saying (in the sequence
as information) "the message ends here".  This is used in a variety of
places such as Unigene, and is useful for users to include in their
submissions.

The question would be: why do you think it would be an improvement?
