You mean ?. here, I assume.
The answer is because what you propose is an incompatible change to
ECMA-262 (all editions) and JS back to its birth, which lets programs
that throw currently continue to run, with possibly disastrous
consequences (undefined flowing into the bank-balance database as
NaN). There is no way that this kind of potentially-bug-hiding
behavior should be the default semantics. It must be explicitly
opted-into via new syntax.
