Because it empirically doesn't work reliably. Every time I can remember
that somebody was complaining about repository corruption (or something
that wound up being repository corruption) it turned out that he or she
was using :local: with the repository NFS-mounted.
I admit that this is a very informal study, and do not claim to have
a perfect memory, but I've heard enough complaints that I would never
NFS-mount a repository and use :local:. Repositories are usually
valuable, and screwing them up is normally a Bad Thing. I don't know
how often it would happen, but once might well be too much.
If I hear similar complaints where the repository was SCSI-mounted
rather than NFS-mounted, I'll be happy to consider that.
AFAIK, nobody knows exactly why NFS can mess with a repository, and
it happens rarely enough that nobody's really caught it in the act.
