With GHC 9.8.1 alpha1 available, the build error is now manifest:

src/Lens/Micro/TH.hs:805:41: error: [GHC-83865]
    • Couldn't match type ‘()’ with ‘BndrVis’
      Expected: [TyVarBndr BndrVis]
        Actual: [TyVarBndrUnit]
    • In the second argument of ‘(:)’, namely ‘vars’
      In the third argument of ‘classD’, namely ‘(plainTV c : vars)’
      In the first argument of ‘($)’, namely
        ‘classD (cxt []) className (plainTV c : vars) fd’
    |
