Performance when watching specific or all values

[hdale94]

Hello,

Just a small question related to performance and the watch() function.

Say you have 20 controlled components in a form, but only need to watch two values:

const [bookingType, forceBooking] = watch(["date", "comment"]);
const values = { date, comment };

This works great, but when developing, I find it more useful to watch all values:

const values = watch();

My question is, at what point would there be a noticeable performance difference between watching specific or all values?
