I think the answer is: both.

crypto_secretbox (and in some cases crypto_box) is used by the open
implementation of the Macaroons bearer credential format to provide sealing
for holder-of-key proofs.

I know plenty of people who use both for "sealing" use cases. libsodium
added a first-class facility for sealing a message using crypto_box with an
ephemeral D-H key as well.
