Since no one is proposing forcing sites to use .xxx,
No one has to propose it openly since the threat is implicit. Regardless of what is said at the moment of creation of the domain, all that a would-be censor has to do is wait [Internet-memory-erasure-period] and say "hey, we created XXX because all the porn is supposed to only be here" and viola.
Viola is a common misspelling (of voila¹) that gets parodied by the more intelligent.
ZOMG !!!!111oneone!!!

1 - voila is the English language word equivalent to voilà. Voilà is French and so should be italicised to indicate it's a foreign word. There's no need to use voilà as one can use voila. Viola!!!!!oneone11!
Or the verb raped in French. I honestly care less about the lack of à in an english context but the i-o swap makes quite an grammatically incorrect yet offensive typo, especially about the xxx TLD.
Yes, if it was a mandate then elementary schools could use basic DNS servers to block then entire .xxx domain rather than having to try and use complex and expensive http content proxy filters that only partially work.
We used to evade the filter at school by entering IP addresses instead of normal URLs. (This also seems to work to evade the IWF.) Is there an easy way to block IP addresses based on a reverse-lookup match against .xxx?
Regardless, I could see this being used as an excuse to shunt porn sites to .xxx, even if doing so wouldn't actually solve anything.
