Makes sense, is you're a 5+ years experienced JS dev.
But a more junior dev (or someone often switching languages between eg JS / Python / Go etc. all day who finds it hard to remember language details) would benefit a lot form the IDE suggestions and validations that can be offered with TS, and move faster at coding with all the extra help from autocomplete and stuff.
So your implicit tradeoff is to optimize for more senior developers. That's OK, but I'm not sure you intended that.
