I've seen that message, and it doesn't seem to actually have any effect on gameplay. I suspect it's meant for realism. Whichever mod (probably RFB) produces that message can't or doesn't actually modify the game's refit behavior, but its creator wants to remind you that for maximum realism, you shouldn't go anywhere until a reasonable amount of time has elapsed. It's a lot like the shakedown trials if you start an SHIII GWX campaign in August, '39. You're not obligated, but the creator has set up a framework for you.
