Delayed gratification is when vets accept that restarts don't immediately show them everything, in exchange for a slowly rising server population. Their acceptance of not getting full maps immediately would be the self restraint. But go ahead and interpret it in the way that tells you I'm wrong and not in a way where I'd be right, if it pleases you more.
The maps aren't the one thing that ruins early game experience. It's one of the many things that leaves an almost total absence of gameplay reward for new players (and in case of inaccessible bases showing up as visited, one of the annoying things). But again, go ahead and interpret it in the way that makes it easier for you, if you want.
