Really? The consistency issue only concerns mapply, I think.

How 'bout changing the formals of mapply to

$FUN $...

$MoreArgs
NULL $SIMPLIFY
simplify

$USE.NAMES
[1] TRUE $simplify

[1] TRUE i.e. add simplify = TRUE and change SIMPLIFY's default to 'simplify'

Then the default behavior is retained, specifying a value for either SIMPLIFY or simplify gives the desired behavior and SIMPLIFY takes precedence over simplify if both are given values. Not pretty, perhaps, but it does the job.

I suppose this could get one into trouble if one of the ... args is named 'simplify', but I do not imagine that is a big deal.
