Is there a reason :wa! doesn't exist?

I like to format my code on build from the terminal. I know helix has support for formatting, but my setup is the problem, not helix. If the build fails, I might need to make a small correction. I try to :w, which fails because the code has been changed by the format. I do :w!, which works. The same workflow isn't applicable though if the correction happened across multiple files, because :wa! doesn't exist. Is this intended or just an oversight?
