Please do explain how at rendering I can change what's in the data at 
https://www.openstreetmap.org/#map=19/53.22594/-0.48389 to something 
more like https://www.openstreetmap.org/way/359607456 so that at 
anything less than z16 you don't just get a mess.  A rendering of the 
latter one (with "emabankment=yes" in this case) can be seen at 

If you say "this is fixable in the tool chain" without actually being 
able to explain how, then we'll have to assume that you actually don't 
know how, and therefore don't know that it is actually "fixable" at 
all.  That doesn't mean that it isn't, but it likely means that no-one 
yet knows how without a lot of spatial stuff in the stylesheet (which 
would be a bit of a nightmare).

And to pick up one other point:

yes, these is one of the most common ways that people do this sort of 
thing.  When I looked into this a while back (mostly in Ireland and the 
UK) I came up with the list at
