​why not.

​once there's been a discussion about that. Can we factorize all this code
into one place, one generic concept ?
This would make things so simple and efficient in the end.

​Can we do that ? That would be awesome !​

​Yes, I suppose.
What do you mean exactly by "high-performance" ?​

​There's been a lot of them written over the years. They're old now and
having a simple way for the user to choose a "backend" would be great.
