Do you perhaps have a non-wikipedia source?

[matthewmayer]

Interestingly Mastercard themselves claim current Maestro account BIN ranges are 639000–639099 / 670000–679999

Perhaps the other patterns were older ones.

[matthewmayer]

Given it appears Maestro is being discontinued, and existing validators and Mastercard disagree on what the correct patterns are, I dont think this should probably be added to Validator

I'm not so sure about that. Cards are usually valid for 5 years or something, and if this plan continued as planned the final cards will expire in 2028. Might still be nice to validate this

[matthewmayer]

also i'd argue its not a credit card, its a debit card ;)
