how about extending the waterway relation with a member role which can
indicate either the "spring" or the "source" in case of a "creation" of
a river by multiple tributary rivers?
Not sure how it would best be called. Source? Origin? Confluence? Is
there a specific hdyrology term for this?
Wikipedia might indicate that "source" is the right word to use.
https://en.wikipedia.org/wiki/Confluence
https://en.wikipedia.org/wiki/River_source
If this is also suitable for a spring, then changing the role spring to
source would do the trick.

While you update the wiki: I feel the "tributary" role also deserves to
be documented in the wiki page. It is used nearly 7.000 times.

That's interesting. I wonder if the tagging of tourism=attraction is
totally appropriate but surely a waterway=source tag is. Presumably the
mapper was trying to indicate that the source of that stream is where
that node is.
I'm going to start using the tag myself and let data consumers figure it
out if they wish. After a while I'll consider adding it to the Wiki.
There are a few instances of the tag in use already.

The point where it starts doesn't (yet) have any meaningful tags,
