The custodians of all Shaheens or the other "dual-use" surface-to-surface missiles are the Army Strategic Force Command, which requires launch command from National Command Authority (via Strategic Plans Division) to launch these BMs. These missiles were not fired. However, IMO, all the earlier versions of Shaheen-I should be stripped of their nuclear role, renamed, and handed over to the new rocket force.
The longest range Shaheen variant is Shaheen-III and its longest range offshoot is Ababeel, which actually has lesser range than Shaheen-III.
Several reasons:
1. Long-range BMs are in custody of strategic forces, i.e., nuclear, and they were not part of the operation, which was purely conventional.
2. Using strategic systems for conventional strikes would also strain the strategic forces' reserves.
3. Something called escalation control through graduated response. The onus of 'action' was put on India, so it would be the aggressor, and in turn Pakistan would respond with QPQ+ (Quid Pro Quo +), meaning retaliation that ups the ante in a manner that increases the cost of aggression. Going after India's vital economic targets early on would have ceded escalation control to India. Then they would have all the reason to strike major non-military targets - including the only three sea ports we have.
Fundamentally, the problem was not with the strategy and its execution but the following two things:
1. Trying to be
Mr Goody Two Shoes and not slipping in few more punches before the ceasefire took place.
- Those facilities from where strikes on Bholari took place should have been decimated.
2. Not having a separate conventional rocket forces equipped with single-use/conventional cruise missiles in the first place. We didn't need a conflict/war to come to realise we needed such a force. This is something that should have been done long time ago. Also, a couple of R&D organisations should have been functioning outside of the strategic grasp, if you know what I mean, and producing conventional systems only. The "strategic hegemony" is unhealthy.

Edit: BrahMos is in the foremost a conventional missile, which we in Pakistan believe India has modified to carry nukes. However, looking into India's inventory suggests there are other cruise missiles that have been specifically built for nuclear role. So, it is a safe bet to assume India has BrahMos available in sufficient numbers for conventional strikes only, without deviating/withdrawing any systems from its strategic forces.
