That's possible, but fragile.  A string-cursor is a distinct
type in Kawa - which is implemented  using the same unboxed 32-bit
int that are used for indexes.  The two can be distinguished at compile-time,
but the JVM run-time representations are the same.  However, when a string-cursor
is *boxed* then a different class is used, so it is possible to distinguish them.

For Kawa I'm focusing on generic sequence functions, including relatively cheap substrings,
so SRFI-130 isn't a priority.
