If that can be implemented without breaking backward compatibility, then
it’d be fine, I think.

Though I think out-of-band means should always work.  For instance, when
compiling SRFI-105 code, one could write “guild compile --srfi-105
foo.sweet”, or
(compile #:from (lookup-language 'scheme-sweet-expressions) ...).
