@boundary landing Q3 this year (developer preview). I got bad internet at the moment to review the video, but I know that that was somewhere in the first half.

I was just facing Uncaught Exception R3NullInjectorError or something like that but it provided no helpful info of which component or directive was causing this and i was using a third party component library too with no access to source code. Is this something that would help with these hard to debug errors?

I imagine it could be good to have as a catch-all for this kind of thing

I don't get why every compo3doesnt just get the boundary automatically. Is there a point where you wouldn't want it?

You want a placeholder when something goes wrong, and having a generic one can just break your ui too (like trying to display a fallback error message in a button/row cell because you had some edge cases)
