Any harm in using the global validity of the domain when retrieving ReCAPTCHA's public / private keys?

Question

Just curious - is there a risk of using a public / private key obtained from ReCAPTCHA for intended use on only one domain, but then we will end its use for another.

I intended to get it for a specific domain, but mistakenly took the public / private key as a "global key":

This is a global key. It will work across all domains.

Is it "bad" to use "global keys" rather than one for a specific domain?
