@Edent part of what I do when copyediting science stuff is check URLs in the prose for just this crap (we try and have them in full so it can be seen in a printed PDF - although there are exceptions). In fact, we try and click through every link too. I’ve had an author make a typo and it go somewhere dodgy. Mind every doi link is relying on crossref to do its thing redirecting to right place, but I know also one of my colleagues does act on error reports we get from them!
