The title pretty much says it all.
What effects would a gtld registration of .onion domain have on the Tor network, is this something to worry about? Or is it something to welcome and slap a web2tor proxy under its entire namespace?
Is it going to impact the security by the percieved notion to the general public that using a regular browser to visit
someobscurehash.onion provides you with anonymity and protection? Or that the website you're hosting under your freshly registered domain name (or hash -- are we really silly enough to register a domain name like that) is safe from evil governments and corporations (provided whoever registers this tld would allow registration of its subdomain)?
