No, we're talking about both BBv1 and BBv2

It's not that it's complicated; it's that it is confusing to the
uninitiated.

I always thought that was better too, but then we constantly hear from
new users who can't tell what the build system is doing, and who find
these "actions" messages cryptic. For those of us who've been around
the block a little bit longer, I think it should be possible to set up
the output preferences differently. For some of users, it has been
suggested, even "actions" are too much -- some would like to see
nothing more than a "rotating bar" | / - \ | / - ...

Well, this seems like sufficient resistance that I'm not going to act
right away, but I'd like to hear more from those concerned about
whether this is a problem.
