Sure, I don't think that is necessarily a bad thing, OPSEC in and of itself is definitely a perpetually unfinished iterative process by its nature. If you are actually interested in this gwern has done some excellent statistical analysis on all known arrests related to DNMs over a few specific timeframes.[0]
The canonical method seems to be (though I can't confirm this, I am armchair commentator as you say) that most sellers wait until they have a queue of several packages ready and then only do one drive to drop them in the mail, so then it doesn't cut into their time or profits dramatically, whilst also giving them an extra bit of protection.
