It sounds to me like you address some bugs in the existing 
implementation, And possible poor design/limitation of the early 
days.

You should probably add 2 as a bug report, then you could have a 
pull request to address them.

Item 1 would be a breaking change, though in my limited view is 
the right direction. It would not be good for a pull request to 
address both 1 & 2 together. Unless of course you end up with 
more feedback contradicting such claim.
