We absolutely need a roadmap and a vision where D needs to go 
when it comes to memory management. Many of us expected this to 
clear up with Walter's presentation at Dconf 2020 but it was more 
basic explaining the concepts with the borrow/checker and was not 
something that revealed any information about any direction of 
the memory management in D.

This is a subject with a lot of opinions but the D project has to 
do through with this despite it demands a lot of work and 
discussions.
