Curious, neither can I (8.1-RELEASE):
(f84104b2)[cyberleo at akisha /tmp/zp]$ truncate -s 256m d1 d2
(f84104b2)[cyberleo at akisha /tmp/zp]$ sudo zpool create pool /tmp/zp/d1
(f84104b2)[cyberleo at akisha /tmp/zp]$ zpool status pool
scrub: none requested

(f84104b2)[cyberleo at akisha /tmp/zp]$ sudo zpool import -d .
status: One or more devices are missing from the system.
action: The pool cannot be imported. Attach the missing
devices and try again.
pool UNAVAIL missing device
Additional devices are known to be part of this pool, though their
exact configuration cannot be determined.

'zpool create' starts over from scratch, and will destroy all data on
the target devices; thus, it warns you if it detects that they are part
of an old pool. You must tell it that you intend to obliterate the old
pool to create a fresh new one. This is intentional.
