If the host is not accepting tempo input from anywhere else (or depending
on how it's all set up, if there's just a single tempo controller that
has a *static* tempo map posted and designated for use), then lookahead
will not be wrong. Ie, if there's a single static tempo map somewhere
that's being used during performance, there's no chance it will change. I
figure this is a common scenario.

I have no direct need for this myself, but was commenting on what's been
said about tempo-sync'ed plugs that can benefit from lookahead when it's
