I'm hardly in favour of dumbing things down, or sacrificing performance. I'm just frequently exposed to issues that are 'magically fixed' by purging the entire browser cache. And I'm just unnerved by the idea of this hash link scheme, we have enough bugs and gaps in the existing system without additional complexity, and that system is pretty damn simple conceptually, yet the bugs remain. Anecdotally, I used to ship jQuery from a CDN for one project, I had to stop for that project I forget why... But I do remember that to my surprise, it turned out that when I shipped my own version of jQuery from my own domain, I got 10% less client side errors reported back to me in Sentry. The world is full of ways to shoot off your own foot, some of them even start out with someone showing you how they don't shoot their foot off.
