No, that applies whenever you have a program which handles a lot of 
containers. I think containers should be "light" for that reason.

It is of very little advantage, IMHO. If it were for a trait which required a 
similar amount of storage but which could not be easily or efficiently 
maintained from the outside then yes, sure.

IIRC, the committee's explanation for making lists carry around and update 
their own length was that newbies might not expect "size()" to be O(n). I 
don't think such arguments are constructive when designing a standard 
library...

Cheers,
Jon.
