I know the immediate answer to this question would be, "... because the user should go through the posted answers to see if anything new needs to be added"

But, here's my point. UX (and most computer related things) changes over time and sometimes even the most highly upvoted answers become obsolete. In case of a highly popular questions (100+ upvotes) with highly upvoted marked answer (100+ upvotes), the answers count (generally) is huge.

Shouldn't there be any shortcut or a hook that allows the user to quickly answer the question rather than having to scroll through 20+ answers?
