I hate to see it go because I too feel it is a step in the right
direction (coming from empty message delimiters). But if it makes the
release more stable and 2.1 behavior is persisted, go for it.

I /think/ reverting this also means that 2.1 and 3.0 will speak the same
wire format. Or, is there something else that changed besides adding the
LABEL bit to the per-message flags?

+1. The old method was broken anyway since durable peers could disappear
and cause memory leaks due to sockets buffering indefinitely. This is
one of the changes that makes 3.0 a must have for me.
