Unprotect or remove Bloomberg BbgResearchPubStorageWorksheet in Excel workbook

Excel workbooks that have used the Bloomberg Add-In contain a hidden protected sheet called BbgResearchPubStorageWorksheet. The fact that sheet is protected prevents certain functions from being performed on the workbook – e.g., deleting custom styles. How can that worksheet be unprotected or removed from the workbook?

Unprotecting from the File >> Info menu claims to require a password, as shown in this screenshot:

(So far nobody in Bloomberg support has admitted that they have anything to do with this worksheet, so they can't provide the password to unprotect it.)

BbgResearchPubStorageWorksheet also appears in the Excel Objects list, but cannot be removed from the VBA editor:

How can we unprotect or remove this BbgResearchPubStorageWorksheet?

(One kludge would be to copy everything else in the workbook into a new workbook, but for a complicated workbook is becomes very tricky to preserve all references, names, and VB code in that process.)

First expose the sheet by going to its properties in the VBA editor and changing its Visible property from xlSheetVeryHidden to xlSheetVisible:

Now the worksheet will be visible and it can be deleted, even without knowing the password that was applied to protect it.
