"he" in this case being me :-) I think the threshold question will always be "Does software X make my life better?" and if it does not, you should ditch it if you can. There is always a huge bias in reporting: People are eager to tell you why they started using your software, but they always forget the "exit-interview" when they drop it again. The reason I hear most often for people dropping Varnish is that they have cleaned up the mess of legacy web-services, or at least transitioned it all to the New Fantastic Platform. Other people drop Varnish for other versions of "this is now surplus to requirements" and I am totally fine with that: I dont want people to run Varnish if it doesn't make their life better.
