I remember when bricking something meant it was totally unrecoverable. Now it means "temporarily not working but will automatically heal".
"Unbricking" will hopefully work automatically, because there is no other option. But that can also fail and there is no way to know, or influence it.
I use bricking in the definition of mobile phone tinkerers .. there are many results for unbricking btw, but I just checked and with the first result it seems that Apple now uses unbricking for activating a new device. Because technically before, it is also just a brick - but here I would agree, that it is not a appropriate term, but rather should be for somehow broken devices.
The JPL doco (>>36941433 >>36942321 ) calls it "Command Loss".
Normally I'd have marked the entire subthread offtopic, but hutzlibu's comment deserves to be at the top, even if it does use the word "bricked" wrong.
