is there by chance an ancient changelog entry mentioning this behavior?
probably not.

well, it seems to be okay for the cygwin port, and it makes good
logical sense.  as long as there's a config file mechanism to
override, then i'd say "yes".  i'd both change the defaults in the
code, and change the default config file to match.  and i'd put a
note in the code somewhere noting that we're not sure why its
necessary to be able to open readwrite -- just so the lucky
volunteer who decides it's time to add direct alsa support
doesn't feel they absolutely have to implement it.
