Review Comment:
> This is "core" and not "api" so I'd rather we not support what we know is
an incorrect behavior imho. We can always send out a dev list thread noting the
change but honestly it feel's like supporting a bug to me
I would rather agree to this.
I faced exactly this case when I started working on a previous outdated PR
for this issue and concluded that it does not make sense to fully rely on the
return type being long, except as a temporary fallback before this is
implemented.
