mono-traversable fails to build with GHC 9.0.1:

test/main.hs:1:1: error:
    The IO action ‘main’ is not defined in module ‘Main’
  |
1 | import Spec (main)
  | ^

Is it okay to rename Spec.hs to Main.hs (also changing its module name) and remove main.hs?

No objection, as long as it doesn't break previous GHC releases.
