Grocery stores are directly selling things to you, and they cost different amounts based on their costs to the grocery stores, handling requirements, etc.

ISPs are like mail services: a letter is a letter is a letter. A package is a package is a package. And a packet is a packet is a packet.

-pedantic-errors -Wall -Werror isn't used in the wild because it breaks whenever a new compiler comes out. New compilers often come out with new warnings, new cases for old warnings, etc. It's not forwards-compatible to make warnings errors.

You should release your code with no warnings on the current compiler, but new warnings shouldn't break everything.
