Resuming RPL non-storing mode

Hi @all,

for those who do not remember or know me (just in case) - I was working the last months on the RPL non-storing mode due to my Bachelor thesis. However due to an organ disease, there was not much progress. In addition during the last weeks I focused on getting better - therefore nearly full silence.

Even there is not much to apologize for, I want to do it, for all who waited for responses or wanted to get the implementation done. Before resuming the work with a now improved health status, just the question whether there were any decisions or plans for RPL? I checked all mails and PRs, but could not find much. But apart of that there are maybe some analogous decisions. Thanks in advance.
