Actually, let's do a tweak _without_ changing a lot of code:

> test = {
>     \once \hairpinPoco g1\< g\!
>     \once \hairpinPoco \after 2 \< g1 g\!
> }

test = {
  \once \hairpinPoco g1\< g\!
  \after 2 \single \hairpinPoco \< g1 g\!

Which is more or less the point of having \single: being able to convert
an override into a tweak when nothing else will do.
