[Tagging] designation=* is a mess in Germany

I've recently stumbled upon some confusing usages of the key
designation=* in my area, so I tried to find out what it really means
and how it is used correctly.
I haven't succeeded.
Of course there is the wiki page  at
which explains that it is used for the local classification of roads in the UK.
But on the same page the usage as a descriptive tag for nature
reserves is also documented.
Looking at taginfo  seems to harden the case for road
classification, but also shows 'shed' in 5th rank.
But I was curious about how this is actually used outside of the UK.
So I did a OverPass-Api query for 500 ways on designation=* with a
bounding box of Germany 
and fed that through a 'grep designation' which gave me a horrifying list .
Seems like I can delete my fresh wiki page translation  and replace
it with a 'just tag anything you want with it'.
Now this might be unfair, as OverPass sorts by way ID which might be a
bad choice for a random sample. But I actually didn't find even one
correct example of usage in there.
I'm so baffled by this, I don't even have a decent question to ask.
Where to start? Modify the wiki according to usage? To what usage?
Modify the tags? All of them? To what?
(I said 'decent'. Not that I don't have questions ...)
Or just slowly walk away from that topic?
