I know many US persons who have Indian and Pakistanis visas in their passport(s), and while issues can and do arise with one or both governments from time to time -- and the outcomes can be somewhat of a toss-up -- people eventually do get the visas and are allowed entry/exit.

The Indian government doesn't always or even generally know if an applicant for an Indian visa has a Pakistani passport when the applicant is using a non-Pakistani passport.
In practice the Indian government does quite often issue Indian visas on non-Pakistani passports of dual-national Pakistanis who neither declare nor appear to necessarily have (or have had) Pakistani nationality.
