Good question. I don’t think it’s disrespectful to leave a match a bit earlier or on the whistle personally. May be premature and foolish to leave earlier. It’s all about context for me. Supporters have always done this haven’t they? Sometimes leave a concert before try the end but only if absolutely necessary to get last train or bus and wouldn’t leave a theatre performance like that. A match is different, though I rarely rush out on the whistle.
