The drastic measure is because of the large amount of code serde generates. The features you describe, by contrast, do not involve much code from a macro standpoint and such macros would not benefit from precompilation. If you're complaining about something that TFA is not an example of, it's a good idea to at least provide something that is an example of it, because otherwise you're just yelling at clouds.
