It buys us time to work on more interesting and more valuable improvements.

Speaking as a long-time lilypond developer, it is my experience that
the errors you point out are not a problem (except for the SCM => bool
conversion).  GUILE's API uses data that can be passed into C
functions efficiently as parameters.  This means that the SCM type
must be a machine word, so the genericity suggested by the GUILE docs
are a joke.

If you feel compelled to change large swaths of source code by
substituting x == SCM_EOL with scm_is_eq(x, SCM_EOL), then I can't
stop you, but to me it just looks like a waste of time.
