Comment (by cypherpunks):

 For as much as an anonymous shared account's opinion is worth, I support
 this consideration. Not only is x86_32 weaker in many ways compared to
 x86_64 as you pointed out, but the processors that are still that old have
 ancient errata which screw with pretty much any sandboxing you'd attempt
 (cache-based privesc, issues with synchronizing NX state across cores,
 etc). I don't think it's fair to the majority for your time to be sucked
 up supporting people who won't be protected well anyway.

 Perhaps in the future, when there are more active contributors to this
 project and it's more mature, supporting x86_32 would be more practical.
 But for now, it'd just be a time waster, IMO.
