[Tagging] Waterway equivalent of noexit=yes?

Would waterway=spreads only be used for intermittent streams/rivers where
the waterway spreads out and evaporates on the surface?

If the water appears to sink into sand, gravel or fractured karst rock,
would we want a different tag instead, e.g. waterway=sink?

I understand that natural=cave_entrance can also be used when a waterway
drops into a sinkhole or other open cave entrance, often found in limestone
(karst) geology areas.
