Yeah, I understood you the first time.
I'm not even going to try to explain my opinion again.
You are adding extra steps with the way you described it.
First of all, you would rarely need to extract the contents of the archive you download. Usually you just select "add fomod" point to the archive itself and wait a few minutes.
Activation is, of course, one or two clicks.
I agree it takes extra time, but if you want to remove a mod it saves ten times as much time. And, as stated, the default launcher has no ability to sort mod load orders. Mods will load in whatever order they were created/installed depending entirely on whether the timestamp is updated.
If you have no problems with load order, and you never have to uninstall a mod, then FOMM is probably not going to do you any good. Most people who use a lot of mods, or experiment with mods will benefit greatly.
I can understand why you don't use it. I'm not sure why you felt the need to tell us you weren't going to use it, or how it could cause you problems at all.
