Here is my personal experience on AF speed,
1. + EF 1.4x II
Still very fast, very close if not at 135L and 400L level.
Based on several years of fast action photography with both, I can tell you that bare 300 f/2.8 IS is not as fast to focus as 135L, let alone with the 1.4xTC.
300 f/2.8 IS with 1.4xTC is slower to focus than 400 f/5.6 in decent light.
When it comes to any BIF, except the largest and slowest of all birds, the 100-400 is not a very good choice at all.
You do know that there is a distance switch, and the IS can be turn off, do you?
What i said is also based on many years of experience. Looks like we two have quite different experiences here. 
You seems likes to go extreme when talking about gears, but with all respect, i didn't see you are pushing your gear to extreme.
Of course, 400L will be better than 100-400L on BIF, and 500/600 will be better than 300/2.8 with TCs for birding. But that is not the point of discussion. What the OP and some others are saying is that 300/2.8 with TCs is a very versatile package and can cover large variety of shootings with better than decent results.
back to 100-400L for BIF, are these 'large and slow' birds? Not the best example and i can get better results with 400L and 300/2.8, but if someone can get this kind of BIF shots, the tool is seems to be good enough, at least for me.
Some time we go the the best, sometime we go for 'good enough', these are two different things.
