Yes. I just do it out of habit so I don't forget something which could
lead to exposure. Habit developed long ago.

Long, long ago, I had a block of IPs and registered domain. Worries
about hacking were relatively new then, I was even more ignorant about
this stuff than I am now, and my gateway/mail unit got hacked. I
immediately split services, hardened the gateway and, in a continual
process of "learning from my mistakes", decided that *always* masking
some site-specific information would help reduce the chance that I would
forget on some critical piece down the road. If nothing else, since I
don't mask *all* site-specific data, it causes me to briefly think.
Since "hoomons" are, indeed, creatures of habit, it is best to reinforce
good habits, even to the point of overkill IMO.

I would rather do unnecessary work and be safer than be lazy and maybe
get burned at the most inopportune time (seems to be the most common
time for *everything* bad to happen).

Since, as I've often stated, I'm really ignorant about a lot of stuff, I
feel no regrets about taking a little more conservative approach to this
sort of stuff.
