For me, the reason is that I don't track the serial number when
generating zones. I don't have any need to track revision counts or
dates for any other purpose, so I don't; I just generate a number which
is guaranteed to be higher than any previous number based on the current
time.
As a nod to poorly written DNS validation tools that tossed errors
rather than warnings, I do start my numbers with YYYY.
Currently this limits me to around 2 updates a minute with the serial
creation algorithm I'm using, but that's good enough for our typical
customer, and we can offer dynamic zones to customers that need it. I
don't think we have any of those left anymore.
