Could/Should calculations be debounced by default?

What is the current behavior?

Currently, there is no debouncing done on any calculations

What is the expected behavior?

I have a bigger form and I can see that calculations are just a tad sluggish and as I don't really need the calculationas to run until the user has actually finished changing the value and not as the value changes.

So I'm just thinking that maybe this is the most common scenario and we could add debouncing by default on the calculations?

THIS.

This also potentially results in incorrect values being added into the form due to field values being changed before the user has finished inputting the complete intended value.

An example of this can be seen using the React Final Form example for Calculated Fields here: https://codesandbox.io/s/oq52p6v96y

Without changing anything in the code example, perform the following steps to reproduce the issue:

• go to the form and enter 5 as the value for "Minimum"
• now attempt to enter 10 as a value for "Maximum"

As soon as you type the 1 in the "Maximum" field (when trying to type 10) the value for the "Minimum" field changes to 1.
This is obvious on such a small form, but could easily be missed on a more complex form and result in unintended data being entered.
