[Talk-GB] Designation: should we begin using prefixes

[Andrew Chadwick]

designation=* has been evolving recently, and has added some open land
classifications:

With the proliferation of these designation codes, would it make sense
to begin coming up with country- or jurisdiction-coded prefixes for
them, similar to the way we denote "national" speed limits?
