All the people recommending lopp's generator, you're right, and I found that, but it's really not the same thing as what I think *should* exist:

A sample conf **with extensive comments on each variable setting**. This existed before, and I believe it still does, but weirdly it seems to be only available if you compile the repo and then run a script, which of course, very few people will do. (+ all the "am I right?" caveats above).

It would be at least something to be able to find those comments/explanations on some doc website or in the repo somewhere else.

Someone mentioned `--help` for bitcoind, that is a fair point, it does cover a lot of the same settings (maybe, arguably, all of them? not sure).
