For most people, working out the ID conflicts and even going to each thread and downloading the mods is a pain.Mods which can't be downloaded by means of Technic or MultMC? Mods that we could have the day they release? Until then, no. If this is the case and FTB might have an incentive, I'm happy to hear that. If it continues to be outdated versions and permissions, it just isn't better.
FTB, Tekkit, whatever other mod pack you want to mention will all have a significant delay between the release of a mod's new version and its update/addition.
It comes down to the facts that there is need for testing, and that too many updates will also means that server admins will hate your pack, as well as users not following threads being lost by too many changes too often.
Keeping up to date with mods usually comes at the cost of doing manual downloads and configs, as well as worlds that are often discontinued quite often (usually not necessary).
I used to check every mod I was using every week or so, updating my world as they went out, but that means actively searching for them and being prepared to spend that time searching, downloading and configuring. I don't have that time now, so I'll gladly play a pack that is two months old, if that pack means that I will really enjoy my time.
It might mean that I don't have MFR upgrades on the planter, nor do I have all these cool new toys from Inficraft (or natura + tinker's construct as it's called now), not even the superb things that MachineMuse added to the armour I like so much.
I think many of us just want to have fun, and even if we don't have the shiny stuff right this second, we will likely have them in a month or three anyway, when others will have moved on to newer things. Doesn't mean that the stuff will be any less cool at that time than it is right now.
