Yes it is small to have a default of 38-bits of userspace. I would be interesting in the opinions of other people on whether it would be acceptable to have the default be sv48 and require applications that prefer fewer bits to specify so with the given mmap hinting.
I think sv48 is a reasonable default instead of sv39. We should fallback to sv39 only if the underlying host does not support sv48.
