Kudos on sharing your efforts with the SQL Server community. Obviously serious thought has gone into the development of the script (not to mention the customizing of it in order to make it of general application for the rest of us).
Your support challenge is certainly significant.
There are some of us who would prefer not to use undocumented features. Hopefully, very hopefully, the next release of SQL Server will officially support a good number of functions which are currently undocumented (even offer additional supported functionality).
Again, thanks for your efforts and thanks for sharing them. Its individuals like you that make it rewarding to belong to this community.
