Default device instead of ``No graphics device is active''

in RHOME/src/ :
grep DevInit */*.[ch]
reveals only a few calls such as
if(!DevInit) error("No graphics device is active\n");
(in graphics/graphics.c and main/par.c).
Couldn't we startup a default device instead of having the error message?
The Default device would be
Unix, interactive: x11
Unix, batch: postscript
Win, interactive: windows
Win, batch: postscript ??
Mac, interactive: macintosh
Mac, batch: postscript ????
[ one could even define
default.device <- x11
in Rprofile.unix, etc.
and have the same .First function
(which could be moved out of profile to base
.First <- function() if(interactive()) default.device()
-- If I remember properly, this is also how S4 behaves..
