DRep voluntary donations onchain metadata+tooling

Eventually someone should facilitate ways for "Delegator to Drep" spontaneous/recurrent ADA donations.
Even just a metadata type code documenting "this is a donation to my DRep"; one-off/periodic; tooling used; misc comment;
Having this boilerplate standard could be a step towards it being implemented by wallets as "Donate to your DRep" buttons, and as "Donate to me" buttons (on things like CardanoPress, Mesh or Vanilla html/js) that DReps could have on their websites/profiles.
Tracking the chain for such metadata could reveal behaviour patterns to later inform what rewards calculations and mechanisms could be reasonable to code onchain.
Maybe DRepTalk could pioneer all this. 🤗
