It only costs a little extra and provides peace of mind.

You're misunderstanding the purpose of ECC here. If you *do* have a
random bit flip in DRAM, ZFS won't detect it, because the corrupted file
block will have been written to stable storage and checksummed as
"correct". ZFS *can't* protect you here.
