If we zfs snapshot -r tank@20220129, all sub-filesystems also get that snapshot.
How to send that single snapshot of tank with all sub-fs's to a new pool (no historical base of snapshots)?
While zfs send -R tank@20220129 will send all sub-fs's, it will also send all snapshots.
(We could later delete all of those snapshots, but that could be a massive amount of extra sending just to delete upon completion.)
There seems to be no zfs send -r functionality.
Final edit: you are correct you can't recursion not handled well (notat for clones!! Each one in as tree needs making separately) I understand the assertion that inheretence the function is being replicated rather than current value of the inheritance but I struggle with use cases where this the most desired value. I'll be making a feature request. When any modifiable property changed from default all children automatically change to inhery. I have an encryptionroot and gen key ds with many non defaults to the active children. Parents and children should have a property to be able to opt out of getting or passinh on inheritance for or all or a set properties. Then zfs send -R -p would act in expected ways. Your case needs an upstream feature often only single snaps want recursive send and being same to recursively create clones from a recursively created snap is an expected option I was surprised to find not present.
I'm pretty sure you could do a zfs clone or something like this below no my original "If snapshots come across just zfs destroy them all; then do your zfs send | zfs recv of the clone without any snapshots." Which was inelegent unresearched and lazy and you don't need to clone anyway just a for loop like so
for ds in $(zfs list -Ho name -r rpool); do \
zfs send ${ds}@20220129 | zfs recv -d newpool; done
But a clone also would work, with a new zfs snap -r and zfs send -R as only one snapshot in new clone. Bit you can't clone recursively so would need a similar for loop anyway. Or rsync it to a nice clean receiving pool and mounted datasets with desired properties if you don't mind losing all zfs-history.
So I'm expanding my solution because it aint that easy or safe and I'm doing it on a live but not critical system soon. In my case I'll also split my mirror vdevs and make some pool and zfs property changes on zfs recv.
Zpool and zfs recursive operations could do with impoving always been a bug bear. And not clear best practice with multiple zsys bootfs, zfs-mount-generator, zfs-zed.service (which does not get restarted after a systemctl suspend cycle!), persistant dataset mounts that do not refelect the state of zfs-list.cache/pool on boot! Cananoical seem to have finished their push for zfs on root and zsys usability. Its not over just because its an ubuntu installer option.

Work out how to install void linux and zfsbootmenu into this hackery and all the zsys and systemd zfs automounts after a new zfs send/receive recursion. Having consistent inherit, and -o desired on zfs receive so important.
