TL;DR

It would be nice if the Lua environment would immediately error when attempting to use a removed feature.

What?

As an example, coroutines are disabled in the control phase, but the error when attempting to use them didn't actually state that, and I had to look around on the forum to find out that the feature was removed on purpose.

I believe that it should be feasible to cause any attempt to access the value of coroutine to emit an error that, "Coroutines are disabled", possibly with a link to a page listing (all of) the ways in which the Lua environment differs from a vanilla interpreter.

Why?

So future mod authors don't spend hours tracking down why their code doesn't work.

The docs are better now (https://lua-api.factorio.com/latest/aux ... aries.html) but I agree that erroring more clearly would be nice.
