Depends on your priorities. Having someone else maintain the code for
you is worth something too. The standard libraries are of variable
quality and there's no real way to know which bits are good and which
leave a thing or two to be desired, apart from experience. 

The hierarchical modules system (in R9) may make a cleanup less painful.

That hex-formatting code is too crappy to be included in stdlib
without a fair bit of work. You can apply it yourself if you want,
though:
