Currently the deletion of an attributes in Attribute Controller also deletes the corresponding POSM entry.
I note the Option name Manager Global Tool "Delete all Option Values from ONE Category of products for this Option Name" does not auto-delete the POSM entries.
There are a lot of tools in Names and Values Manager and I would not want to integrate all of them with POSM, but a comment / a documentation entry would be of interest, to clarify your position.
