I added these comments on github, but for the benefit of anyone  
interested:

I think it makes sense to use "key" rather than "name" to fall inline  
with the config table, and it might be a good idea to namespace it as  
<r:config:setting> so that it loses some potential to clash with any  
other extension out there that might use <r:setting>
