Using casts doesn't hide warnings so much as tell the compiler that you have examined the context and want it to convert something anyway.
Leaving warnings is worse than using a cast because library users are left to wonder whether there are problems in the library, can't find their own warnings and errors among your warnings, and can't build when they prefer to treat warnings as errors.
