Although I agree with the implied sentiment that "the Perfect is the enemy of the Good Enough" (especially for low-profile personal web-presence) and that naval-gazing about protocols can become a counterproductive rabbit-hole, sometimes it can also be risky to oversimplify in the other direction without at least parenthesizing the caveats too. For example this "HTTP/1.1 must die" site points out how desync attacks make HTTP/1.1 robustness a bit of a game of Whack-a-Mole. For certain sites (even some personal sites) this can occasionally matter.
