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.
