FWIW, "others" have tried changing
/home/egreshko 2001:b030:112f:2::0/64(rw,sync,insecure,no_root_squash,no_subtree_check)
to
/home/egreshko 2001:b030:112f:2::0/64(rw,sync,no_root_squash,no_subtree_check)
And the mount from an F33 system still succeeds.
The entry for "man exports":
secure This option requires that requests not using gss originate on an
Internet port less than IPPORT_RESERVED (1024). This option is
on by default. To turn it off, specify insecure. (NOTE: older
kernels (before upstream kernel version 4.17) enforced this re‐
quirement on gss requests as well.)

/run/sysconfig/nfs-utils had: GSS_USE_PROXY="yes" -- wonder if GSS is somehow at play here?
