If your entire core team does not want threads, then police your company's slack to make sure people aren't using threads. The engineering org at my company decided that threads should be used as much as possible and when people don't reply to a previous message using a thread, they get told to use a thread next time. After months of doing this, noisy messages that are just replies to other messages have decreased significantly. Another alternative is having people always mark the checkbox that says "Also send to #channel". Vocal minorities shouldn't drive product decisions.
