This is _not_ the way Linux works.  We don't have a stable API  
_precisely_ so we don't have to "hack around" our API.  When the API  
is broken, we fix the API, therefore it doesn't get "hacked around"  
nearly as much as a so-called "Stable API" would be.  The development  
cycle is *accelerated* by the fact that an important API changes are  
_OK_.

Wrong again.  "Guided" implies that some overall authority controls  
everything that goes on, which is inherently unscalable.  Look at how  
inefficient all the governments are!  Look at how inefficient Linux  
kernel development was before BK and git!  When Linus had to deal  
with the thousands of patches individually, that was the development  
bottleneck.  As it is now, the merging work that Linus alone used to  
do is now divided up across a combination of Andrew Morton, Greg KH,  
and many valuable others (who can't all be listed without making this  
message overflow the mailing list limits).

Linux development scales _now_ better than any other software (open  
_OR_ closed) on the planet; recent patches from 2.6.X to 2.6.X+1-rc1  
are 25MB in size and constantly growing.  If you can come up with a  
development model that works as well and prove it in production, then  
good for you.  I don't expect, however, to see any closed-source  
project come close to the rate of production of Linux; even  
_Microsoft_ couldn't afford as many man-hours on a single codebase  
for long.
