Important to know.
I did not check the documentation for 5.0 
is that problem properly documented?
It could avoid wasting time answering questions.

You missunderstood me here.

I meant that 
we should declare the main aim of 5.2 
as the attempt to overcome the vector weaknesses 
Naturally based on your efforts and the improved format.

The second point I was trying to make was
that we should then refrain from other big changes for 5.2
and only focus on improving the vector side.

This will shorten the time until your vector work is available for everybody.
