The lock is *already* exposed. For better or worse, this is the API
we've chosen. And since the need for the lock will hopefully decrease
over time, I don't think we should put effort into improving it.

Ha, I'd wondered how much of the documentation (and locking) around
this was relevant in 2026. Not something I plan to tackle in the near
future, though :D

Curl is also in the "thankfully no more" bucket, but we support older
Red Hat installations that don't have the improvement yet.
