Yes. There's no guarantee that any of the messages currently in that
mailbox adhere to that attribute though, so you can't make assumptions
about any individual message. But from a configuration perspective,
it can be useful to at least provide a better default value(s) than a
MUA-specific hard-coded value.

We allow different "identities" to be configured in our client -- e.g.
I send out messages under a number of different
e-mail/header/signatures. It is *very* handy to have the sent-mail
messages saved to a different mailbox for each identity. The RFC
defines the \Sent flag to include any mailbox "used to hold copies of
messages that have been sent." By this definition, each mailbox
should be flagged with \Sent.
Or you have an existing account that contains pre-existing "Sent",
"Sent Mail", and "sentmail" mailboxes. All of those are valid sent
mailboxes under the \Sent definition.
