Besides the increased risk of an ALoD (Apple Logo of Death) and Apple apologists telling you that you've got too many apps (hehe) I don't think there's anything to worry about. Except the ridiculous install/upgrade times (I'm at 15 minutes per app now, with 70-75 installed) ...
Anyway, good luck! 😉
