In my CS subfield we use latex, but switching journals still tends to be a huge pain, as many use extremely brittle templates that can easily create incompatibilities and make the paper not compile if you don't spend considerable amounts of time debugging after making the change. In addition, different journals have different length limits, word limits, structural requirements, one vs. two column (which may make your figures overflow), what goes in the main text vs. supplementary material, bibliography format changes that sometimes are only partially handled by bibtex, etc., so basically what the post says. At least, ChatGPT seems to be very good at cutting text to try and fit length limits. And no one gives up with a paper, although this might have more to do with location than discipline (the academic evaluation system in my country is heavily metrics-based, having indexed papers is what makes or breaks careers). People resubmit and resubmit and resubmit, typically to venues with a progressively lower bar, until the paper is accepted. In CS we also have competitive conference publications and, at least in my subfield, they don't have these problems to such a great extent as journals (as at least their latex templates tend to be decent, and some of them have the same length limits). One of the reasons why I prefer conference to journal publications.
