Yes, but IETF suggests that your UA should publish a <tuple> with
<contact>mailto:yourmail at domain.org</contact> and <basic>open</basic>.

Imagine I'm at home but my phone is in DND and "offline" status.
Anyone could come to my home and call me (using the human voice).
Should my SIP device publish that "I'm available by human voice at
home" (<basic>open</basic>) ?

It seems that IETF SIMPLE group claims that SIMPLE presence should
cover *any* presence status. This makes most usual cases unclear and
complex.
IMHO a user could publish "I'm available on mail" and also provide an
email account, but it shouldn't mean a "open" status at all as this is
SIP, no SMTP/POP.

When a specification tries to cover all the world and dominate all the
rest, it becomes... COMPLEX.
