On reading the spec, it's not clear to me whether an IKEv1
implementation which supports ECP-based DH (rfc4753) with preshared keys
but not ECDSA (rfc4754) is considered to usefully implement this
specification.

As a practical matter, the ECDSA piece of this spec is likely to be the
largest and last piece built -- given a working elliptic curve codebase,
plugging ephemeral ECDH into an IKE implementation is a much smaller
problem than building ECDSA into both an IKE implementation and the PKI
client codebase, tools, and keystores it relies on.
