I did not make such agreement with you, and don't think obfuscating
code with printf->puts conversion is a good idea. If there's
codingstyle document I missed somewhere, please point me to it.

If you think global conversion is a good idea, please do it, so that
old code does not serve as a bad example. But I don't think it saves
any size, compared to speed of serial line it does not save any time,
either.
