Commented Feature: Add farm account to db_owner role on search databases after creation [21520]

To remedy a potential issue as written here: http://techmikael.blogspot.no/2014/10/caution-if-you-have-used.html, would it be possible to patch this using autospinstaller, granting the correct rights to the farm account?

I just did a report when re-creating my SSA.

Ran PowerShell as the SPInstall user. SPAdmin is the farm account. I scriptet up the SSA, then went to the UI and added my local miksven user as an admin. Boom... lot's of errors in the ULS on db permission issues and query does not work. I then manually gave back db_owner rights to my searchadmin user on the search db and it worked again.
