It was more of the "nobody bothered implementing it yet" variety.  The
varieties presented by Ian Hulin would all be mappable to a form of

\repeat coda #n { ... } \alternative { ... }

on the input side.  One "just" needs to make it do something useful, but
the \unfoldrepeats could be quite the same as for \repeat volta.
