SCS v 3,0 (see Gibberlings3 ongoing analysis of the mod)Sorry, but it's version 30, not 3,0 ... the reason why the "analysis" thread is so long is that there hasn't been an update for quite some time, it's one of the most popular mods to throw in to a combination with mods, and including megamoded games, it was stable on it's own. Add BP and you'll have a whole lot of messes, especially if you have 50+ other mods that break all sorts of stuff, just like the BP without the entity fixer(what ever its name is now)... Or add the Spell Revision, Item Revisons or others and depending which version you throw at it, you'll have different kinds of mess each time... the mods were/are developped at the same site, so they spill over a whole lots. The SCS ones tried to incorporate the SR, IR etc, but those version 2's, not betas of the v4's.
The SCS has been in the BWP installs from sinse the BWP even came out, cause the SCS(I) enhanced the BG1 AI in BGT-weidu, and the SCS(II) did the same for BG2 portion. The BP hasn't been until recently when the v181 came out, after the component slice and dize.
Yes, no and yes and a bit of everything.
Converging former SCS i + II into 30 (right) was like always = the sum often is more than the individual pieces. Yes, many parts of it have been around like since forever, still it now acts differently (the other factors you mention - fully agree). The reason not to say it is expert is the active support you have since the enhancement is worked on.
This is a hard nut . for all the reasons you give. It is quite old but somehow new in its current form. And you sureley remember that SCS i + II back then required a lot of knowledge about which component to install and when (and with which other mod or not).
