I've reviewed all the open issues that come up when searching for "getrandom" on the issue tracker, and closed all the ones that were either out of date or rejected based on PEP 524 being accepted and implemented.
For the remainder, I either wasn't clear on whether they could be closed or not (in which case I posted a comment asking Victor to take a look at them), or else they were clearly still valid and I posted a relevant status update.
Doing a similar search for "urandom", I checked the ones where the titles seemed relevant and commented where a status update and possible closure seemed appropriate.
