I had the impression that these warnings are on by default without
-Wall mostly by accident. When I added -Wdangling-else, I wasn't aware
that it would fire without -Wall, and dblaikie unsuccessfully tried to
move -Wswitch to -Wall here:

I'm just as happy with tweaking the comment above -Wall in the .td
file instead and not changing any behavior (patch for that attached)
if you think all these warnings should stay on by default.
