Nintendo does this as of latest firmware. It's desirable because it removes the only usage of util::SNPrintf() from os library, which means programs which don't otherwise use SNPrintf do not need to link it into .text. This saves ~0xD40 of .text as of time-of-commit when successfully unlinking, and e.g. reduces our sm (and other modules) memory size by a page.
