I don't know which classification would be good for my purposes (low
zoom rendering), but currently we have not a single one defined nor
used in practice, so I want to start with something. It doesn't need
to be perfect, maybe simple length=* tag would be useful - but we
don't even have it currently.
I've just found that length=* tag is quite closely connected to
waterways (almost 72% uses):
https://taginfo.openstreetmap.org/keys/length#combinations
Taginfo does not show such combination with rivers (it probably omits
anything <1000 uses), but it's 446 lines already:

I'd like to add length=* as Additional tags/Useful combination in some
Wiki articles, like:
https://wiki.openstreetmap.org/wiki/Key:waterway
https://wiki.openstreetmap.org/wiki/Tag:waterway%3Driver
https://wiki.openstreetmap.org/wiki/Tag:waterway%3Dcanal
https://wiki.openstreetmap.org/wiki/Tag%3Awaterway%3Dstream
I hope length combined with some simple classification (like
order:classic=1) can be quite useful in case of low zoom rendering.
