You are incorrect. Time-stamps merely prove that data existed prior to some
point in time. There is absolutely no need for anything to be published in the
blockchain to create a timestamp. Indeed, efficient timestamps don't actually
publish any meaningful data: for efficiency you always combine many timestamps
into a single merkle tree; a merkle tree tip digest is meaningless data by
itself.
OpenTimestamps does in fact use OpReturn rather than something more efficient.
But it does this only because the efficiency gain isn't significant enough for
me to have gotten around to improving it. Reducing fee costs by ~10% isn't a
good use of my time.

If your concern is the data being public due to OpReturn vs Taproot, you are
confused and need to think more carefully about what exactly you are doing.
