I been ill/busy myself.
Liquid JS would be a good solution.
For any native stuff being able to have that level of out of the box logic to easily expand your back office without going fully custom addon would save people heaps of time and effort.
For many just being able to have simple “if have title display that else use default” and like to help compliment their custom block grids etc would be great.
Then for anyone building more custom build solutions being able to build web components if they want but to just be able to tap into liquidJS to render out the data with logic that comes with it would be great for them as well.
It would save heaps of time having to try build out something to replace what used to be possible.
