It is a tradeoff in my experience. Being interrupted by small requests does jank me out of my flow but on the other hand immediately responding to a problem can save them hours of being stalled by some issue. It's simply necessary as a senior developer. For the same reason I immediately often stop whatever I am doing when I get a code review request as it allows others to get a specific issue done faster and iterate on it instead of having to look for a different task in the meantime and come back later to the issue under review. On the other hand the tradeoff is not worth it if the issue is not an immediate blocker.
