I generally agree. I understand how this condition will probably never
occur in arch.

I discovered this when I decided to prefix or postfix pkgver and/or
pkgrel with some values dynamically. As I'm not sure If this is possible
in any other way, I wrote a function to do this and called it in package

I'm probably the only one who needs this. So, I edited the condition
to respect FORCE and applied to my personal tree:

IMHO, silently deleting files (especially outside $startdir) is always
bad. The rarity of this condition is a more compelling argument.
