PATCH won't fail when running partial updates, but it won't silently drop the attributes that it doesn't support. So from client side, there is no real way to understand when to include that attribute which was added in a later version.
Yes, I see the problem with that.
We need some way to associate attributes with a minimum Core version, which we can get from
/systemendpoint. Although, for now, it probably is an overkill. I will do some static stuff to take care of this.
What happens when someone runs from say git head though? /system/version won’t keep up with that, and besides, it’s going to become an increasingly big compatibility matrix over time.
How bad do you think would it be for Core to silently drop extra attributes and only use the ones that it needs?
I think it could be problematic, as Steve points out.
I don’t really have a good answer, and I’m wondering what the state of the art is. Maybe we should ask some experts for advice (we do have some friends who are experts in this).
