But that is the same when you develop a web page. You check develop it checking it in your favorite browser. But when you get closer to the finish line you test it out in more browsers so you are sure it works in all of them. The same can be done with a theme too. After all, it is just a team. It is not like I am developing all my web pages checking them every other second in IE, just because 60% of my users use IE.

I think you are completly wrong when you call a choise of theme a huge mistake, as long as you make sure it works for everyone before release.
