Very logical.
Advantages:
+1    Might be amenable to automation.
+2    Robust with respect to re-formatting.
+3    Supports any variation of Staff.BarNumber.break-visibility (I
think).

Disadvantages:
-1    On a given line, bar numbers increase in strange and surprising
ways, giving potential for confusion.  One cannot just count from the
start of the line and announce a bar number.

For that reason alone, I'm inclined to favour:
o    Counting the bars of the top visible staff of the system, whilst
o    Allowing discontinuity at the start of each line to accommodate
other parts that might have more bars in the previous line.

But that's just a personal preference.  I wouldn't want to impose it on
anyone else!  (and I'm prepared to accept the need to fiddle with bar
numbers manually at a late stage in the editing process).
