I concede that an individual's response should also be within some amount of reason in a given context. If your team isn't responding to anything in a reasonable amount of time, that's a serious problem. To me, ticket status and Teams channel questions are
way more important than the vast majority of emails or standups. However, in your situation, there's some benefit (mainly to you) to standups.
You're in a tough position, it sounds. You're a lead, yet likely restricted to leading technology and not so much people. I don't know what your leadership style is, but I've noticed some people are treated like bosses for merely acting the part, so that's something to consider.
Also, what I meant to say was that a person should skip standup if it actually benefits their productivity. They should show up to some standups, perhaps most. Hypothetically, standups could be done well, but I don't usually experience this. I don't think people should never show up to team rituals.
