The server doesn't need to parse the body. I'm not talking about returning one string for the response, I'm talking about returning this:
 return 200, {["Content-Type"] = "text/plain"}, "Hello world!"
instead of having to do this:
 return 200, {["Content-Type"] = "text/plain"}, {"Hello world!"}
or this:
 local first=true
return 200, {["Content-Type"] = "text/plain"}, function() if first then return "Hello world!" first=nil else return nil end end

If you return a string to the server, it will need to be parsed.
Considering that this data was probably in variables before it became
a string, it's rather wasteful to prepare string output for a parser
when it could be assigned to a var in the API. Or...

Table, fast; string, slow.
