Paul and Gordon, my page points to Ned Wright's tired light
critique and acknowledges that if distant supernovae light
curves are genuinely stretched in direct proportion to the
observed redshift then this constitutes an excellent disproof of
any tired light theory explaining that redshift.

That is not the only argument against tired light. The argument
from the CMB radiation is also very strong (tired light does
not preserve 'black body'-ness of a radiation bath, but the CMB
is thermal to very high precision, requiring incredible coincidences
for TL to work.)
