There are some who would consider the choir the benchmark, and both fixed
JI and 22 an approximation.

Also, the choir's bandwidth is flexible, and does not necessarily give the
same effect as a fixed deviation from just.

I don't think 22 is an approximation to any music performed by any existing
choir, but hopefully that will change.

My statement referred to random, uncontrolled deviations from 12-tET, in the
context of solo singers accompanied instrumentally. Professional vocal
harmonies do tend toward JI intervals.
