Build failures in wai-logger-2.1.0 to 2.3.5 due to missing bounds on fast-logger

v2.2.6 and newer were failing with errors like

Network/Wai/Logger.hs:107:10:
    A pattern match on a GADT requires the GADTs or TypeFamilies language extension
    In the pattern: LogNone
    In an equation for ‘logCheck’: logCheck LogNone = return ()

As a Hackage trustee I have created some revisions that should prevent users from encountering these errors.

See e.g.

• https://hackage.haskell.org/package/wai-logger-2.2.5/revisions/
• https://hackage.haskell.org/package/wai-logger-2.2.6/revisions/

This issue is just for your information.
