I don't but I think about it. Not a bad time of year to re-queen. If it goes well, she gets you well set for the fall / winter. If it goes south, you have time to fix it before the cold weather. BUT.....if you just adopt the position that each colony gets a new queen in July, then you're not taking into account your best queens. Or even ones that are sturdy and productive. Plus, human nature will lead you to believe that your new queen is going to be better (unless she's a clear dud). So you may choose to keep a new queen that lays a hot hive thinking that you're still better off even though if you hadn't swapped your queens out you'd be thinking about replacing her anyway.
Theres' nothing wrong with the date for almost all parts of the country. Lots of keepers pull frames in supers, extract, clean up and assess. It's more about the thoughtful approach for a hobby beekeeper than the date on the calendar.
