Introducing Modern Comments in Microsoft Word

OK, why on Earth would you "improve" comments by:

1. Making it harder to see where the comment points within the text by eliminating the in-text highlights and dotted line connecting the text to the comment box; 
2. Requiring the comment to be "posted" by either using an enter arrow or keystroke command rather than, say just typing it normally;
3. Requiring the user to open a drop down to select "edit" just to be able to continue or revise the comment;
4. Wreaking havoc when the document is used on different versions of Word; and
5.  Eliminating spell and grammar check within the comment so people can see what a terrible speller I am?

Was there some compelling user movement to make inserting and utilizing comments more difficult so less people used the function, or was this simply a make-work project for a bunch of folks who needed to show there leaders they were busy?  No doubt that the task force who devised this "improved" version did not understand that requiring users to take extra steps to use the tool each time and making it harder for the reader to see where the comment points tool is not actually helpful.  Or perhaps the update team was full of folks who believe that the 17 people who believe writing documents in Adobe is somehow the "bomb" and Word was falling behind by not adopting the stylistic and functional ineptitude of such a program. For the love of God, please allow those people who actually use the tool to have the option to use the normal/usable version that has been with us without issue for the last decade, or at least a version where you don't have to hit three select buttons to insert a **bleep** comment.  I suddenly miss WordPerfect!
