[Tagging] Deprecation of associatedStreet-relations

Most don't. Right now JOSM is the only one I use that does. Especially 
most mobile editors don't... some just flat out don't even show you 
relations.

Fully borken or not. In my opinion a assiciatedstreet relation that does 
not include every element is broken. At that point all the advantages 
are gone.

Obviously not much better, but I think people are less likely to just 
remove a addr:street without noticing than a relation. So I fail to see 
how is makes AS better as everyone claims.

Often I do this to convert a node into a area.

Sometimes I remove stuff by accident realize it later and instead of 
going back just replace it, because I did more stuff in that time and 
don't want to lose my work.

Why would it have been prepared? And why with AS but not with 
addr:street? Most associatedStreet-relations I found in Germany did only 
include houses where someone actually mapped the housenumber. I did not 
find a single one where all houses in a street were included, but lacked 
other addr: tags.

If a street is split several times and a user knows he can find all 
parts in a relation I would no longer consider that user a newbie.

And that's where I disagree. Removing a object for a relations is as 
likely as missing a addr:street tag. In addition the consequences are 
worse for the associatedstreet relation, because you assume it's 
complete when it actuall isn't, which makes it kinda pointless.
