>Why can't embedded devices use certificates?

Because they have neither a DNS name nor a fixed IP address.  I ran into this
just last week with a customer, they couldn't use certs for their embedded
devices and couldn't use PSK because the browser vendors have chosen not to
support it.  As a result, they abandoned the use of TLS altogether and went
with SSH.
