Thanks for the clarification. This really kind of depends on where rancid
is run. In a campus/client env. I see your point but we also have more
static parts where this is usesful information. There it actually is also
useful to see what ports actually have changed. But you are right maybe no
worth it overall.
But thanks for pointing out the OSC part. What we see on most of our Nexus
infrastructure is every night:

- !Flash: debug:      124053    Jan 18 05:38:00 2017  bootvar_debug.log
- !Flash: debug:           6    Jan 18 05:38:00 2017  bootvar_debug.meta
+ !Flash: debug:      124872    Jan 19 05:38:05 2017  bootvar_debug.log
+ !Flash: debug:           6    Jan 19 05:38:05 2017  bootvar_debug.meta


And this:
- !Flash: logflash:       87092    Jan 17 05:43:42 2017  accounting_log
+ !Flash: logflash:      136367    Jan 18 05:43:35 2017  accounting_log



Which is quite annoying...

Well then you have to fix it for this as said:
XXX-cc# show vtp status
Service not enabled


Cheers,
