As I have "pointed out many times", yes there are ways to work around these
problems, but DHE hardening is presently actively breaking TLS ecosystem.
And for what?

Finite field D-H is taking attention away from ECC, and I think ECC is
clearly the future. What good reason is there for continuing to support it
instead of focusing on ECDH?

I want a TLS ecosystem with less workarounds, less errata, and less
complexity. I see no reason to keep DHE around.
