This is major change. Hopefully it will not break anything in XC when 4.4.6 is released. Just a suggestion:
Include a big red text across the screen upon install or upgrade to 4.4.6 that will warn about these changes even if you have to make it with an "agree" checkbox so no one can miss it. Don't count on XC users to read the change log or the forum.
Of course make it look nice and presentable
I know some will find it annoying (me too at some point) but better safe than sorry
