they need to do something, yes make it work. at least..   people laugh at its functionality,  I cant pay my bills on line for some sites, follow links or use dropdowns,,  I don't see the value in edge? just years of lip service so far.
when  I try to cast video to my TV, from edge it is frustrating as it is unreliable to paly a video with out several crashes,  maybe it has value to corporations  and they forgot about the consumer again..? good luck with that. my android phone streams 100% reliably and same video quality !
  I used to be able to ask Cortana or Bing to find a song and it would find the song and open it in grove for me to buy  they broke they , 
now google and amazon do that    no  echo system here ,    nothing to keep me hear after years 
of following these things ,   but the 80% completion project rule for Microsoft has been evident for many years
now.
