Bitkeeper taught Linus by his own admission that there was actually a
reason to using a SCM for the kernel to begin with, and helped drive
some early git design princables which he also briefly mentioned in the
google git talk.

So I hardly consider this a mistake looking at it from a historical
perspective.

I am really sorry to hear about SCST's bad timing wrt to the evolution
of git, but I hardly see this as an acceptable excuse for poor mainline
workflow.

Well, if we are going to start talking about car analogies, then I have
one for you.. 8-)

Using a centralized SCM for kernel subsystem workflow in the year 2010
in akin to trying to make a modification to a 18,000 RPM capable engine
in a Ferrari F1 (eg: Linux Kernel), tuned to run at the *highest* levels
of international competition (eg: LKML).  But instead of using the tools
(git) that where explictely designed the F1 engine by it's creator (eg:
Linus aka Enzo Ferrari), you end trying to adjust your F1 engine's
killowatt per litre displacement output using a broken FM tuner knob and
rusty spare tire jack from a 79' Ford Pinto.

Best,
