fieldExists is missing

[georgmzimmer]

Describe the bug
According to the documentation, fieldExists should be a function of the formApi that returns true if the field exists. This function used to be part of the formApi, but now the function is missing! I need that function, or some way to do the same thing.

To Reproduce

go here, and click the button labeled "Demonstrate that fieldExists() is missing!"

Any updates on this? I see fieldExists still defined in the type but missing an implementation. Is there some other way to find if the field exists? I haven't been able to find one when looking at getFieldState or FormState values
