Upper bounds lead to a better user experience.

That's what I'm disagreeing with. I do not believe that, overall, the PVP is giving users a better experience. I've had a huge downturn in reported errors with Yesod since I stopped strictly following the PVP. It's anecdotal, but everything in this thread is really anecdotal.

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. Erik
