Separate from the issues surrounding enforcing declared policy, putting metadata into identifiers seems like a bad practice. 

Besides the issue of scalability — do we really want a SSID that looks like “mnot_nomap_guestsallowed_privacyguaranteed_prettyplease” — this proposal is squatting on ALL suffixes; someone who wants to define the “_guestsallowed” suffix, for example, now can’t do so because it’s in contention with _nomap. 

Never mind that it’s retroactively assigning semantics to potentially existing identifiers.

These issues seem very similar to those raised in the draft-nottingham-uri-get-off-my-lawn. It’s very tempting for us as standards bodies to encroach upon user-visible identifier space, but doing so brings a number of concrete technical problems, as well as a higher concern; that these name spaces are explicitly defined to be under user (or administrator) control, and taking that control away retroactively shouldn’t be something we do.

Cheers,
