Are precrisis feats relevant?

the monitors talk about the first universe as if it is a streaming history into the next universe. Are those feats valid?

For some characters like Spectre and Darkseid.

"New Earth" is taken from bits and pieces from all universes, so yes...some of the feats are valid again.

The fact that the characters remember themselves in "precrisis" times alone may unlock some of those.

you really had to create an entire thread dedicated to this question?
