ZFS feature compatibility?

I have a few machines on which I've been hesitant to run 'zpool upgrade' 
as I'm not sure of the (boot?) implications. They report like this ..

imb_at_toshi:/home/imb> uname -a
FreeBSD toshi.auburn.protected-networks.net 14.0-CURRENT FreeBSD 
14.0-CURRENT #25 main-eb61de5b78: Fri Jan 22 10:03:02 EST 2021 
root_at_toshi.auburn.protected-networks.net:/usr/obj/usr/src/amd64.amd64/sys/TOSHI 
  amd64

imb_at_toshi:/home/imb> zpool status
   pool: zroot
  state: ONLINE
status: Some supported features are not enabled on the pool. The pool can
         still be used, but some features are unavailable.
action: Enable all features using 'zpool upgrade'. Once this is done,
         the pool may no longer be accessible by software that does not 
support
         the features. See zpool-features(5) for details.

Is it safe to upgrade the root pool?
