10000?1000000?or no limit?
there's some rpc tests which tx 1 zootoshi to 2-3k t-addresses, https://github.com/zcash/zcash/blob/3920292b4368a42cf56c7dc16fa324b60e24a8c8/qa/rpc-tests/wallet.py, but there's no indication whether this is the actual limit or not.
in the wild, we have a case for shielded to publics tx's where 1500 was the ceiling. see https://github.com/zcash/zcash/issues/1851, https://forum.zcashcommunity.com/t/zcash-pool-zec-nanopool-org/4655/103
thanks a lot (20202020)

we really need more documented cases.
if others have hit wall at a low|larger count, pl0x share specs; amount, count et cetera
