Shoehorns are designed to help slide your foot into a tight shoe. If interested, you can find out more on the history of Shoehorns here (https://en.wikipedia.org/wiki/Shoehorn).
Essentially, they help with a snug fit between foot and shoe.
Where Shoehorns do not work is getting a size 11 foot into a size 10 shoe.
Not happening, not working, not worth the effort.
So the question becomes – Are you trying to ShoeHorn a small Feature into that next release to make it more snug OR are you trying to ShoeHorn a new Feature with no requirements, no understanding and no resolve into it?
(Answer: You don’t need a bigger ShoeHorn, you need a bigger Shoe/Release).
