I ~~am sure~~ hope somebody™ already thought of this. Feel free to advertise your project here.
P.S.: Image transcription:

Somebody should take document type conversion from Pandoc and version control from Git

And build a frontend around it
I've been using Quarto a lot for Data Science work and it uses Pandoc under the hood I recall.
Not sure what you're envisioning by Pandoc + git, but the RStudio IDE has a git integration and a WYSIWYM Quarto editor.
Quarto looks quite interesting indeed, thanks for pointing it out!
For those interested it's an "Open-source scientific and technical publishing system built on Pandoc"

Like a data format inhabiting the centre of that conversion graph they have on their website, basically a superset of the available input types, that is then version controlled by git, and can be exported to any of the output formats, in a neat frontend that removes all that complexity from me. :D
Quarto user here, I use it for my blog.
There is also a vscode extension for WYSIWYM editing.
