I'm not the one you're asking, but: Two problems.

1. Meetings. Senior people have more meetings than junior people. Technical leads have more meetings than individual contributors. As you grow in an organization, you have more meetings. If you're an introvert, that's draining. If you get your dopamine hits from making things work, that feels like your time is being wasted. But in fact, you are more valuable to the organization. It's just less fun for you.

2. Being asked to support legacy stuff is almost inevitable, especially if you wrote it and it's important stuff. But if it's important stuff, the organization really needs to increase their bus factor on that stuff.

Also, supporting legacy stuff is often less than a full-time job. It means you can try to work on something else too. You just get interrupted, which destroys what you have loaded into your brain and kills your momentum. It's annoying, it's inefficient, and it would be better done by someone more junior.
