Does anyone know whether any ECDHE based cipher suites were added for
SEED for TLS?

I don't know what the background for this request is, but I'd like to
point out that we had similar discussions in the past about obscure
ciphers (look for brainpool curves) in the past.

This is my personal opinion, but I think it is widely shared among many
in the community:
It used to be that the TLS community valued supporting as many ciphers
as possible. But this has more or less ended with TLS 1.3, which is
part of a larger realization in IT security that unnecessary complexity
is usually bad and should be avoided.
Instead the trend is to support a small set of algorithms that are
generally considered "okay-ish" (there are always minor ups and downs
of certain cipher choices) and leave it with that and not seek to
support a wide variety of algorithms.

I'd oppose any specification of new cipher suites without a good
justification, and I think this is an opinion many here share.

And I just see an I-D for AEGIS-128L and AEGIS-256, albeit not for TLS. There seems to be no limit to new algorithms!
