There are two motivational factors behind write-simple:
speed and the desire to generate output that does not
use the reader label notation. We both agree that
write-simple is necessary, you're just claiming that
speed is not as much an issue.
My point about SRFI-38, however, was that it says:
This SRFI permits but does not require replacing the
standard (write) and (read) functions.
which was very unfortunate, because you don't have
a guaranteed write-simple (with or without error handling).
