Two people don't make it a majority opinion, but if this was a meeting
this opinion would get a second.

I don't know where everyone is on the spectrum, but I also strongly
dislike -Werror yet do like -Wall and tend to get rid of warnings.
-Werror is good for continuous integration systems, not so great for
releases or active development.

-Werror kind of seems like Stack Ranking, good for use during brief
periods, but poor for long term continuous use.
