The question is historical. I think you can't have been making your immense industrial build in the years immediately preceding `Wed Aug 15 14:54:44 UTC 2012` when `yesod` signed on to Brian O'Sullivan's plan of omitting upper bounds throughout Hackage (a plan which on your view must itself have arisen from O'Sullivan's madness and incompetence or vested interest in a non-existent FPComplete that he never had anything to do with, since there was of course no problem at all, it was just a fiction he cooked up). `yesod`s 2012 act of compliance was on your view calculated by FPComplete (founded 2013) to take over Haskell by means of a then non-existent `stack` tool (2015). On that day, the installation of `yesod`, a perfectly innocent web-related library, required the installation of 145 distinct Hackage packages, as you can verify with a couple of commands. The previous record was held by the pandoc executable which in the form it took on that same fateful day (pandoc-1.9.4.2) required the installation of only 47 distinct packages. Yet in the previous years unlimited amounts of ink had been spilt on the pandoc list and #haskell explaining what was going wrong when pandoc users tried to build the newest version with the feature they had prayed for. With `yesod` things were now completely out of control. This had nothing whatsoever to do with `yesod` or anything else being in itself broken. `yesod` presumably did actually need e.g. `x509-validation` and `aeson-pretty`. Other packages went over to the plan announced by O'Sullivan too, though most of them reverted. --All of this, on your view, was part of a hostile take-over plan by the non-existent FPComplete. You are by the way of course benefitting from stackage in ways you are not recognizing, though, like me, you are not a regular stack user. It is very familiar that before stackage, there was much less coherence among the Hackage libraries. Things were best about one month after a new ghc was released.
I don't understand why you keep bringing up bos's question. How does one person wondering aloud if PVP is good or not make anything I've said inaccurate? As the bulk of your post is responding to a strawman you created, I'll allow you to provide the voice for it yourself.
It's clear that you weren't around then and don't have the historical knowledge necessary to have a view about this. This isn't stopping you from spreading absurd libels.
It is "clear" to you, because that is what you want to believe. You have no basis for that belief, it is incorrect and silly, but it makes you feel good because you think it allows you to dismiss what I said.
