I am just guessing here and have not started studying

#1) Isn't that where the lingual nerve is? You hit that bad boy and you are screwed!

#2) isn't the gingiva on the max palatal non-movable, therefore it being fixed and keritanized it will be a pain in the butt to displace from the bone and therefore more difficult to heal

u need ATTACHED gingiva to reposition a flap
there is no attached gingiva on the mand lingual region,[the lingual nerve is only in the ptergoid space,running dital to the third molar]
like wise no attached gingiva on max palatal region[the palatal mucosa is a continuation of the free gingiva]
