That would certainly encourage adoption of try/catch.

I don’t think that matters:
-----
{
use feature 'errorobject';
eval { 9 / 0 };
}
say blessed $@; # prints something
{
no feature 'errorobject';
eval { 9 / 0};
}
say blessed $@; # prints nothing

Whenever $@ is populated, the relevant logic would check to see if the active feature set dictates putting the object or the string into $@.
