I'm not sure what you mean by "won't be cool."  It doesn't break any  
functionality as far as I can tell, and successfully adds  
functionality for systems that support it (e.g. Foxylicious).  People  
are already using parent.child syntax for tags [1] [2], and it seems  
to be working just fine.

You could, but that doesn't give leave any indication that  
httpsubscription is meant as a subset of software.  Not particularly  
important in this case, but "politics.green" is quite different from  
"construction.green" or "color.green".
