Logically, that makes sense.  However, try asking a group of R users
how to cite R (or how to find out how to cite R).

I think it's a good idea to make the default list signature as good as
possible, I just don't think it will have that much effect.  Supplying
a small reproducible example when reporting an error is "common-sense"
(how else will the developers/others be able to replicate it?) and yet
it is very rare (not just in R, but in any project).
