That's really just the difference between news and articles. News events (big trials, disasters etc) are highly time-sensitive and if your income depends on display ads and Google, instant publishing is crucial and something that comes up on RFPs for such systems. Workflow where content is created by multiple people isn't as well understood but can be a source of incredible friction and productivity killer in publishing.

The argument is sometimes made that this doesn't apply to simple blogging and that SSGs of course aren't aimed at pros, but I can say with some certainty that the segment of bloggers who can and want to publish with Git etc is infinitesimally small and quite possibly 100% represented on HN :) That's fine and great if it works for your use case but it pains me a bit to see people re-discovering the very old and disproven model that SSG represents. It's a) highly niche and b) counter to many current and new requirements in content publishing.

The main argument for it is performance but I don't see how it improves on Varnish - albeit w cache warming - and tellingly edge cases of cache warming are getting replayed in SSG increasing complexity. In fact dynamic systems often forgo cache warming as not worth the result much of the time (and can do it selectively), but you don't get that control at all in an SSG system.

This really hits home for me, because I'd love to use a CMS, but I just haven't found that is: (a) easy to use (b) easy to customize.

Just to single out a shortcomings I've recently found: multiple authors with multiple languages, defining short and long version of bio/tagline. The tagline is displayed at the article, which may be tagged with multiple contributors with different roles (author, translator, reviewer), while the author page displays the long version.

I've spent days to figure out what plugin/theme combination (Wordpress or Drupal) would enable me this single feature, and I couldn't figure it out.

Yesterday evening I gave up, and now I have <200 lines of code in Dart (using markdown and mustache), generating static pages that were annotated with metadata, doing just that. To be honest, I'd trade it any time for a decent CMS, I just can't find any.

No, the main argument is for security, then cost (software updates cost time), then perhaps performance, though as you point out there isn't much difference with a properly configured cache.

Clearly static doesn't suit all sites but if the site is infrequently changed and not too complex or dynamic it is sometimes the best choice. If you have highly dynamic content with multiple authors static is clearly a terrible choice. This is not a zero sum game, there is room for both approaches.

Given even the White House uses a db backed CMS, security seems a pretty weak argument to be making. Yes, static HTML is sometimes an excellent choice but it doesn't represent any kind of new solution in the space.
