To put simply, the answer is no, there's no "long poll" endpoint and no
plan to add it to the spec.

The reason is it doesn't make sense to ask for new entries unless you know
they're there - by first calling get-sth to learn of a new tree head.

Generally the protocol is designed for auditing for tree consistency by a
client/monitor that observes STHs, fetches entries for the tree at the
specified size and validates the root hash published matches the one
calculated from the entries.

IIRC there are monitors that offer a polling service.
