Re: [whatwg] Fetch: please review! (Anne van Kesteren)

some input (I know, I'm a newbie in this mailing list so maybe i'm stating
or asking the obvious, atleast for everyone else):

   1. for clarity: The legacy chapter should be near the end and not the
   first chapter, I couldn't understand most of it because it uses terminology
   from the Fetch Standard, explained later.
   2.  What is the purpose of fetch standard?  replacing http/html
   requests? something else? yes I read:

   To unify fetching across the web platform this specification supplants a
   number of algorithms and specifications:

   but I'm not sure what does that means. since this is a big change,
    changing the way tjhat all clients and web servers work (maybe this is why
   the legacy part is so early in the doc? because almost all the web is
   legacy?)

   looks to me like something that could be breaking the web (xhtml 2.0
   anyone) And I'm not sure for what benefit? some new url schemes? a more
   correct and rational http fetch behavior? we already got used the the
   current behavior. changing this should come with a very good reason. if
   anything. The rational for "Fetch" should come before anything else.

Thanks for the chance to input on this
