Nice to see that people are eager for this to be implemented 
I hope and believe that I’ll have time to work on this pretty soon.
FWIW, I think the amount of work will not be large. Optimistically, I would estimate that the changes would be released in a couple of weeks or so, but please, take this with a grain of salt. (In general, estimation is hard.)
I will reply to this thread again after the uncertainty of those estimates is significantly reduced.
I am interested in chatting with people about their specific use cases. This may have been covered earlier in this thread, but it’s pretty long, and maybe was not focused on this specific question. If you would like to maybe be mentioned in a future Global RnD, send me a private message.
I think one of the main uses is liquid staking. You can read more about it in our docs https://docs.waterneuron.fi/ or in our forum post introducing WaterNeuron: Introducing WaterNeuron
The implementation of the MVP of this feature is now in the master branch. Therefore, this will be released as part of the next set of NNS canister upgrades.
In general, the NNS team proposes upgrades on Friday, and DFINITY usually votes in favor of those proposals on Monday.
I will be on vacation for a couple weeks starting on Thursday. The NNS team is arranging for the rest of this to be taken care of while I am gone. I do not expect that they will need to do any additional work, other than be aware that this feature is being released, and stand by in case something happens, which seems unlikely.
There are some additional materiality metrics that I’d like to implement, but those will be released as “version 1.1”, so to speak, of this feature. Someone else on the team might work on that while I’m on vacation, but I would assume it won’t be done by the time I get back.
