Both warnings are avoidable and considered bad style, which makes them appropriate to include in -Wall.<o:p></o:p></p>

The reason that -Wincomplete-uni-patterns wasn't originally made part of -Wall was due to worries about noisiness (<a href="https://ghc.haskell.org/trac/ghc/ticket/4905">https://ghc.haskell.org/trac/ghc/ticket/4905</a>), but that's not a valid concern. -Wall
is intentionally a moving target, if you want to stay Wall-clean you accept that new compiler releases may entail some work.<o:p></o:p></p>
