No, sorry. One package failing to load does not necessarily leave
"Emacs in a bad state", at least not in theory. That's why
ignore-errors, condition-case and (require x nil t) exist, for

So predictable exceptions are handled by those functions already.  But now things are just borked.
Your way makes a bit more difficult to detect the problem, and a bit
more likely that it will be missed and subsequent requires fail
without warning.
This is a valid point. 

But, hey, it's your code, put it whenever you think it's right.
