My guess is, they had to run it in parallel. So many things relied on the old UI, not to mention run/cmd commands (printui, netplwiz to name a few), that simply just putting modern replacements for those things would have broken every single printer share, user credentials manager, etc., there is out there. So, they decided to run them in parallel. Smart choice if you ask me, since they own most of the desktop market share, if they decided to make a 180 turn on this, that would have cut a significant portion of their user market share… not to mention companies that heavily rely on MS products being pissed AF.
