I certainly agree with that.

One option may be to create an egg that modifies and exports all the
affected code.  For example:

(define (with-input-from-file str thunk . mode)
 (apply core:with-input-from-file (expand-path str) thunk mode))

And then you can import the module with or without a prefix if you
want automatically-expanding versions.


A second option would be to provide a global boolean parameter
such as (expand-pathnames) which would enable or disable automatic
path expansion.
