That is strange. The new specifier tags based mechanism is supposed to 
touch (create/remove) only those specification with a "custom" tag.
Could you find out where this is happening?
 
 IMHO, Custom should not be touching _anything_ it doesn't put on
the
 specifier itself.  But that's arguable.
 
 It is not arguable that it is evil for Custom to touch any
 specification with a non-null tagset that doesn't include Custom's
 signature.  If I put a specification with a tag on it on a specifier,
 Custom had better leave it alone. 
The tag based mechanism should do neither of these.
