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.
