Not that it matters anyhow for most roles you neither need nor can afford to hire the best and brightest away from their current role which they probably love a lot(being the best gives you the ability to choose great places to work). So unless you're looking for a tech lead you're going to be looking for great, much better than average but not specifically the best and for those conditions PHP will give you a much larger developer base to choose from every day of the week.
As for the last point I think you're really reaching here to find a negative. A large community to handle bugs a hindrance? Seriously? And your alternative ideal solution is some people down the hall in your office that know how to use the language well?
