But you also tell people to use stackage and yesod-platform, which
fixes a lot of packages to a specific version, IIRC. That means that
not having upper bounds is kind of moot.

As a counter-anecdote, almost all build-related problems we've had in
the past year have been (http-)conduit or tls related, due to the lack
of upper bounds.

That's a fair point, I left out X factors in this analysis. So I'll say something else instead: back when I followed strict PVP compliance, I still got a lot of reports of broken builds, and my maintenance overhead was very high. Since I dropped PVP compliance and implemented alternative solutions, the reports I've received have gone down dramatically, and I spend far less time on maintenance.

So color me unconvinced that the PVP really made a big difference in users' experiences.
