You might expect a lot of tags with magic prefixes like `email=....` or `contact=...`; not that it's your concern as the implementer since tags have no internal TO semantic meaning. As such it might make data entry more error-prone with typos like `emial=...` and overall requiring operators to know magic word prefixes to do things in their external tooling.
   
   As an operator, I don't intend to use tags as purely informational.  They become a means through which I can supplement ATC with information necessary to automate processes required to operate a CDN.
