TSConfig having a lot of options isn't a selling point though; you shouldn't need any of those. That said, the flags and strict mode are intended for when you have an existing "sloppy" JS codebase or mindset.
You shouldn't need anything (except strict mode) in a new TS project.
That said, TS is quickly becoming the antithesis of what Go tries; every release for the past few years I've seen now are all features where I'm like, "I will never need or use this". Some conveniences have been improved on - like better type inference - but that will mainly allow for cleaning up workarounds.
"some orgs with specialised needs" are going to be legacy projects, either older TS versions that didn't have the features that it does now, or JS codebases. This isn't generally an issue with Go projects, most of which are greenfield. That said, there's some X to Go conversion projects that produce less than ideal code though, like usage of the `interface{}` type that at this point is a code smell.
