I agree, but I was merely pointing out that a problem with pitch markings being incorrect or the pitch dimensions being wrong can be grounds for a match being replayed.
I have seen plenty of teams who have pressured a ref into playing a game, mainly when the state of the pith means that it should probably be postponed, only to start complaining when they are losing.
Not every team just goes out because they play for fun, quite a few teams take their games seriously, especially when it comes to things like county cup competitions, or at the end of the season title or relegation deciders.
It's those times when there's a chance it could cause you issues, although as I've said previously I've never seen a pitch with lines as bad as the ones shown in the OP so I doubt it would ever actually come up.
