Why not having a level with no false positives? This would avoid to disable the
warning globally.

IMHO, using it when a union is involved is likely to generate false positives.

The warning only looks at the single expression it quotes which isn't really
enough to discover you are doing right.  It tries to be helpful - if you know
better then disable the warning.
