Instead of these values that would need to be dynamic to be generally
reliable right?
Everyone might need something different.

I thought about the same and wondered if this script should get a new
optional argument.
If passed it will use this new argument instead of $refbranch

That would allow any user today to be able to continue to use it as-is
and anyone else can for reliable behavior define the branch to look
in.
