I can see the usefulness of removing resources. As for if resources over write each other, sure it happens, but I never really considered that an issue. As for bashed patches, I use them, got no problem with them, they are easy to make, you just build one and press okay a few times, lol.
Say that you see a new high res armor replacer for a set of armor.
Then later you decide to install a more general set of texture replacers for all armor. The first set would be overwritten by the second.
Only BAIN allows you to swap those out without the added task of having to uninstall/reinstall all the other aspects of each mod. Oblivion does best on a defragmented drive and so the less you can do heavy handed file swapping the better.
I'm curious what parts of BAIN you think are useless or needlessly complex. Granted it is needlessly complex if all you want to use is 10 mods, yet even with 10 mods it handles them more thoroughly than any other installer.
I think probably it is more the case that you just haven't found a need for all that complexity. Let me assure you though that all the features are there to serve a purpose. Why would anyone bother to code them for no reason at all?
wha .. I turned patriarch ... just noticed that. Odd names - patriarchal is not considered a cool thing in my world.
[edit] Crojob-
Also the point of having everything controlled by BAIN is that it will visually give you the info on under and overwrites and save you from having to remember what went in when and what overwrites what.
