What exactly would be the value of that?

There is work afoot, or at least on people's to-do lists, to mechanize
creation of the outfuncs/readfuncs/etc code directly from the Node
struct declarations.  So special cases for particular fields are going
to be looked on with great disfavor, even if you can make a case that
there's some reason to do it.  (Which I'm not seeing.  We've certainly
never had to do it in the past.)
