Note that, although exceptional, some waterways can flow both ways, according to tidal, floods, if a connected estavelle is absorbing or discharging water... Even if it is unlikely, this tag could be of some use to highlight the fact that the waterway is not subject to such stream variations.

Subject: [Tagging] Use of oneway=yes on waterways
According to the waterway=stream wiki page
If a flow exists, the direction of the way must be
downstream (i.e. the way direction follows the flow)
As of today there is a very small percentage of streams (17593
ways according to taginfo, 0.23%) with oneway=yes.
Is there any undocumented purpose? Is it ok and safe to delete
oneway=yes tags for streams?
The same question can apply to drains, ditches, canals...
