In fact it does (as do most other resolvers), the priming is a process where an initial query is sent to the root server address taken from the root.hints file and the resolver caches the current root NS answer and additional sections. Whether it takes the root.hints from configured file or compiled-in defaults is only tangential to the priming process.

Theoretically, as long as there is at least one working IP address in the root.hints, any sane resolver should be able to recover and start using the current IP address set of all the root servers. It just might take a while…
