exactly - i'm not complaining .. just understanding the confusion
I don't think anticipate deprecating df in favor of "zfs list", but
df_zfs or additonal flags to df might be helpful .. perhaps a pool
option, and some sort of easy visual to say that the avail number
you're looking at is shared .. perhaps something like this (sorted
output would be nice too by default):
# df -F zfs -xh
Filesystem size used resv avail capacity Mounted on
...
log-pool (457G) 120M --- (447G) 1% /log-pool
log-pool/butterfinger
(457G) 24K 10G (457G) 1% /log-pool/
butterfinger
log-pool/swim [50G] 24K --- [50G] 1% /log-pool/swim
thumper-pool (16T) 1.1T --- (13T) 8% /thumper-pool
thumper-pool/home (16T) 46K --- (13T) 1% /thumper-
pool/home
essentially just some way to tell at a glance that the capacity is
either (shared) or a [quota]

yeah - i'm thinking it might be helpful to see reserved capacity here
by default, or at least have a switch for it instead of having to
alias "zfs list -o
name,used,reservation,available,refer,mountpoint" .. i'm always
thrown at first glance by that one:
NAME USED RESERV AVAIL REFER MOUNTPOINT
log-pool 10.1G none 447G 120M /log-pool
log-pool/butterfinger 24.5K 10G 457G 24.5K /log-pool/
butterfinger
log-pool/swim 24.5K none 50.0G 24.5K /log-pool/swim
thumper-pool 2.63T none 12.9T 1.11T /thumper-pool
thumper-pool/home 163G none 12.9T 45.7K /thumper-pool/home

my point as well - meaning you're never sure if you're going to get a
seat especially if there's a rush .. sorry looking back it's kind of
a bad analogy
