This feature has been added in survival 2.36-1, which is now on CRAN.
(2.36-2 should appear in another day or so)

Hi David,
Thanks, but I don't quite follow your examples below.
I wasn't really sure they did anything useful anyway.

The tendency is to use residual-like diagnostics on the entire dataset that
was available for model development. For test data we typically run
predictive accuracy analyses. For example, one of the strongest validations
is to show, in a high-resolution calibration plot, that absolute
