[Mimedefang] vcs extension

I just got a legitimate text vCard attachment in my quarantine with a .vcs
extension. It's in the list of bad file extensions in the default filter.
Why is that? Is this extension used for some bad binary formats? Or can a
vCard carry dangerous macros? I'm trying to decide whether to remove vcs
from the list, since calendar files for appointments do seem like a
legitimate thing to receive.
The sender was xtime, which seems to be an automotive dealer-customer
management system, and it assigned application/octet-stream as the mime
type of the attachment instead of a proper calendar type.
