As has been discussed pretty thoroughly already, this is not variable 
data but a completely fixed, static bit of package-specific support 
infrastructure. It's just like a package specific library or other 
component file whose name never changes and which that single file 
services all running instances concurrently.
The "library or other support file" just happens to be an empty 
directory in this case.
As such, something/lib/<package>/something is really the most correct 
place. Just pretend you can't hear the word "temporary" in the 
description of it's purpose.

Maybe the install target that creates this directory could also place a 
small text file in the directory explaining the directories purpose?
"This directory must exist, even though no contents are ever placed 
here. see http:.... for details"
That shouldn't affect it's use as a mount point and helps the system to 
self-document.
