Those arguments are somewhat flawed.  If we stick to "BK did it that way 
and it was first", then following that logic we would also carry a lot 
of CVS baggage because "CVS did it that way, and it was the most 
successful of its kind".  Still, we decided not to follow CVS nor BK in 
many ways already.

As for the fraction of people complaining being a small fraction of 
current GIT users: that is easily explainable by the fact that most 
people who would have grown the complainers group are simply not GIT 
users anymore since they were turned away by GIT's current user 
interface issues.  The only complainers remaining are those who see 
value in the GIT technology but who would like to bring more 
intuitiveness to the GIT interface instead of going for the alternative 
technology.  And those kind of people are always few.

The counter part of that is the possibility to fall for the "ivory tower 
syndrome" where seasoned GIT users feel they are well satisfied with 
what is currently available and unwilling to consider changes that would 
reduce the barrier to entry for new users... simply because they are so 
used to the way things work that they can't see why others have problems 
with it.

Agreed.  This is why the current discussion led to a proposition that 
allows for "pull" to remain as is but to have a "get" version that would 
be the alternate (saner) version.

Do you have comments on my proposed syntax (that would be implemented 
with a git-get command) which I think doesn't really look like cogito?

Agreed.

I agree with you in general, except for the "pull" behavior which is 
really really odd.  Maybe it made sense in the BK context, maybe it is 
fine _once_ you get used to it, but otherwise it is really overloaded.

Agreed again.
