Have you ever regretted keeping everything internal versus opening the team to remote specialists from different time zones?

Ever catch yourself wondering if bottling up all the dev work inside the company was actually smarter than bringing in remote folks who live halfway across the world time-zone wise? A couple years back we stuck to our small local crew for this one app rebuild, thinking it'd keep things tight and communication instant. Ended up burning out a few people because we couldn't scale quick enough when features piled up, and honestly, those late-night Slack pings started feeling like a bad habit. Anyone else dealt with that tug-of-war between keeping it all internal for control versus cracking the door open to specialists in totally different hours? Curious what tipped the scale for you guys.
