A bus module older than its in_force answer read as not held, so a merge
before mesh-catalog #166 is live would silence every ask until a person's
bus upgrade. Such an answer now falls back to the check main makes (is the
list sent to the bus's machine the one composed now), says the reload is
not confirmed, and each case names its own remedy: push <node> for a list
behind or not allowing it, a ~5 s wait for a reload, the bus upgrade when
an older module's list cannot be judged.
