Assumption: when you say "tag" it's the Digikam (keyword) tag. 

Maybe digikam won't remove tags when they have disappeared from the sidecar?

Or when the XMP element where they are stored isn't in the sidecar? That could 
actually be considered a feature, as it would prevent losing information just 
because a poorly behaved other program doesn't conserve XML elements it 
doesn't understand.

Afaik, sidecars in Digikam are an extra, not an essential part of the data 
structure and storage. So the database is the standard, and modifications 
should be conservative..
