I'm not sure what to do about this particular config line.  IIUC, this is
configuration that could appear by manual intervention or automatically;
which is a subject of annoyance for me, that ephemeral configuration like
this would appear in the show running config.

I understand how this could be annoying, but that some might wish to
retain it, while others may wish to filter it.  I'm inclined to add a
knob similar to FILTER_OSC, but it seems like there are 4 classes of such
things; beyond what FILTER_OSC filters, there are 2) this auto-configuration
(VTP vlans), 3) auto-configuration that can also be manually configured
(secure-mac), 4) informational stuff that changes frequently (flash space).

It does not seem like one knob could/should address all of these.
