I'm curious why you ask.
Are you considering an implementation that cannot support such use?
In practice your assumption is probably right for "normal" URIs, of the
sort that someone might put in a vcard or on a real business card.
These things are more likely to arise when the URI is learned through
signaling, such as in a Contact address.
For instance these can arise as GRUUs. (And yes, there are now some
implementations of GRUU.)
