I know someone that is willing to implement this feature, but they are waiting for merge of rfc to open a Pull Request with initial implementation.
As I understand the RFCs are for defining scope and design requirements for specific feature. And when the design is finalised RFC is merged. Then someone opens a PR to implement it.
If you were imagining some other process it would be beneficial to acknowledge change of development phase from designing to implementing.
P.S. The readme in the repo is supporting my view.
There is an official polish Neon Genesis Evangelion voiceover that aired on TV once. All the other versions are with subtitles.
