BAZ> At this point I wonder if jhb has added (enough) spares with an earlier MFC of another change or whether we'll break thing again?
That is why I asked about this on arch@ and was waiting several days for
people opinion :-). The response I had was: do MFC if jhb does not have any
plans for the vop spares (and he does not).
I can change "MFC after" to 2 months or undef, and I will be fine with any
other solution proposed.
