cough might be true for a 20 year old banger but prettty much
anything younger will have the computer(s) connected, alarm etc. OK
all in various states of "standby" depending on how long the car has
been switched "off" but all still there. Some vehicles have a
deliberate "sleep" mode so that the battery isn't flattened by all
these devices before delivery or other known periods inactivity.

As for the OPs question, the battery will be fine so should all the,
permenantly connected electronics. Indeed disconnecting the permenant
12v may well cause more problems as the computers may "forget" their
settings or reset to basic defaults. Not to mention having to reset
the time on your clock and enter the anti theft code into the radio...
