Let's keep this particular tone to a minimum. It probably wasn't intentional, but it won't be received well. FTB won't be able to reply on a mod-by-mod basis. To determine if its "safe" the way you're hoping they'd need to look the mod over in detail, test it out, basically what they've been doing for months with the mods that are in the list. Just throw it in and see what happens. Start a dedicated thread about it if you run into problems or want to share your experience. You're not the only person interested in OC, other people may want to discuss it in a proper thread.
