because the affected users are just users and apparently not important enough to consider when setting versioning policy.
Users are important enough to consider, but their needs should not trump all others. In particular, (nearly?) all software on Hackage is given to users at no charge. Developers invest their time. Their needs are important too. If policies make it too troublesome for developers to maintain software or publicly post it on Hackage, they will just stop posting it. Obviously there is a balance to be struck, as if you make things too hard for users then there will be no users. The problem is that the PVP is putting a considerable maintenance burden on developers but it's not even clear there is commensurate benefit to users. Often it's hard to get different packages to work together because upper bounds are too tight.
