A proposal like this comes along every few years & never really gets off 
the ground. "Long hiking & cycling routes" by their nature of being long 
are rarely traversed completely; people hop on-off of them in short 
sections. So a "systematic survey" is highly unlikely.

Most of what's been listed here I would describe as every day mapping. 
I'm unsure what benefit adding another tag, which will soon be 
inaccurate, will bring.

There are a few validation tools to keep an eye on the integrity of 

Can anyone recommend some others?

Historic GPX traces remain relevant. Individually they are not that 
accurate. Having a collection allows a mapper to iron out inaccuracies & 
estimate a mean average route.

If you want to register a path being physically non navigable, an email 
to the authority responsible produces better results than marking it in OSM.
