This pattern occurs several times in the GoGoD database. In all the cases I looked at, white didn't jump out of his seat and say "That's an overplay! Now I must punish you with death!" In fact, I didn't ever see white try to exploit the bad aji in the area right away. I couldn't even find two games where the situation is handled the same way. Below are a couple of ways I found played.
If white later gets the

stone in place, this becomes possible:

White seals black off from the center.
Or, there is this possibility if white doesn't get the

stone in place above:
$$W

$$ | . . . . . . . . . .
$$ | . . . 6 2 3 8 . . .
$$ | . . . X 1 4 X 7 . .

is a common tesuji.
There is even this crude way to play when white just wanted to ensure life:

So I would think the lesson is, the two-space extension may leave more gaps for your opponent to exploit, but there are no obvious "punishments" in a general sense. If your opponent plays it against you, use your reading skills and work out some solutions that look good for you in the game. Once you have those sequences worked out, don't rush to play them, but keep them in the back of your mind (or, to paraphrase Iwamoto Kaoru, as "arrows in your quiver"). Don't fire one too early, but keep them for when you know which arrow to fire.
