Check if a Recoil value is available without triggering it?

[phuctm97]

Is there anyway to check if a Recoil value (atom/selector) is available without triggering its effects/default value in a selector?

Currently in selector there is only get method will always trigger the atom effects/default value, would be great to have a has or isSet/isDefault getter that only checks & subscribers to a value without triggering it.

Current workaround is to create a separate boolean atom just to start that value and update when it's appropriate, but it feels redundant.

I would use atom without default value and return undefined if there is no value set.
