Initially it didn't make sense to me... but it looks like type striping is really the way to go for future TS.
There's the "types as comments" proposal[1] which could even land on browsers one day.
I started using the erasableSyntaxOnly setting in my tsconfig to get ready for this.
At this point we should really prompt all the AI power in the world we have to create a TS replacement. It seems grotesque.
(Iām not disagreeing to remove it. It just took me a while to find out what happened to it)
