Port randomization helps against blind spoofing, but once an attacker is on-path or owns a resolver, it stops mattering.

If an attacker owns a resolver DNSSEC stops mattering too; from the resolver to the stub-resolver, the protocol collapses down to a single "yes we did DNSSEC" bit in the header.

The bigger thing here is DoH, which has very real penetration, and works for zones that don't do anything to opt-in. That's what a good design looks like: it just works without uninvolved people having to do extra stuff.

I think DNSSEC supporters, what few of them are left, are really deep into cope about what transport security is doing to the the rationale for DNSSEC deployment. There's nothing about DoH that makes it complicated to speak it to an authority server. The only reason I can see that we're not going to get that is that multi-perspective kills the value proposition of even doing that much.
