Current behavior

at https://docs.nestjs.com/standalone-applications isn't clear which nestjs features aren't supposed to work when using NestFactory.createApplicationContext (+ app.init)

Expected behavior

I'd like to read that middlewares, pipes, NestModule#configure, etc won't be evaluated in the standalone mode.

I'm not sure what is expected to work in such apps and what is not, I just have few guesses

What is the motivation / use case for changing the behavior?

people sometimes complain that few features that aren't working when using the standalone mode.

Would you like to create a PR for this?

I'll create after testing every feature that I can recall
