I have log_spacemap enabled.

zpool import -f -a -o cachefile=none -N
"This pool uses the following feature(s) not supported by this system:
 com.delphix:log_spacemap (Log metaslab changes on a single spacemap and flush them periodically.)
All unsupported features are only required for writing to the pool.
The pool can be imported using '-o readonly=on'."

Accepted for post 0.8.1: https://github.com/zfsonlinux/zfs/pull/8442#issuecomment-511918033

(But this could happen with the import of ANY zpool from another system. For instance from a non zfsonlinux system with different feature flags set.)
