Well the SuperPack project appears to be offically dead, so 6.4.2 is the last release. I ran it, it works fine, but it includes a whole bunch of gameplay mods. (not FCOM standard ones, or even widely known ones, just a bunch of stuff the author likes I guess) Mods that I really didn't want, and since the installer program gives you zero options about what components to install, the only way to deactivate said unwanted components is to go back to Wrye Bash, rebuild the bashed patch, etc etc. So why bother now since I'll have to go through most of the hassle I hoped to avoid.
An installer idea is still great idea as FCOM is somewhat of a PITA to install, especially if you don't have a lot of time to devote to it. (and searching through the spotty documentation on how to use & understand Wrye Bash) Double that if you want to add a bunch of other hefty mods to your game, Deadly Reflex comes to mind. If someone makes an FCOM installer I think it absolutely must give the user options about what components to install. If someone ever wants to make an FCOM + other popular/big/compelex mods installer I will give them a nice tip & be its hype man. I'm sure many other people would too. If I was rich I'd start a fully paid mega mod installer project.
