I did a few quick tests and this seem to work OK. All in all i feel your feature proposal is performing reasonably good now. When more users will enable to test and use it. What could happen is some issue or a glitch could emerge you will need to address then. But this is true for a lot of other features in FreeCAD 017 too. Therefore as far as i am concerned i don't see an issue if this feature gets added to FreeCAD 0.17.
I really had to look that one up in a dictionary:
Hopefully we are referring to the first part of the "or"verb
Push one's lips or one's bottom lip forward as an expression of petulant annoyance or in order to make oneself look sexually attractive.
‘she lounged on the steps, pouting’
with object ‘he shrugged and pouted his lips’
