Well, this part you mention, for instance "though this fact has received little attention so far".

A change on the standard candles calibration would be a huge deal for cosmology and galactic astronomy (and other fields) and would not be taken lightly at all. There are all sorts of ramifications from this and if astronomers aren't all in an oof about it, it is because big proof is needed for big claims.

And a change in the standard candles calibration is indeed a very big claim.
