I frankly love this change. For along time I wanted a way to catch such extensions and non stadard behaviour. For the long term, we could create 3 macros, legacy for old unmainatined code (the -std=c89), standard which will be the result of this porting and a future one with some bonus flags. standard is the default and the other 2 are opt in. We need to encourage upstreams to stop using UBs and extension when it makes sense (They for example break when defaults change like this and certain UBs can also prevent putting -O3 and can cause security issues). So I recommend -fsanitize-trap=all to be in future for now (I would like putting -Werror but thats probaly going be too much). Good to see Gentoo also helping out. We should talk to some of the big upstreams to put these flags in their CIs. That way we will less issues down the line.
