I'll move this into the discussion area because I think it's not a question that is necessarily going to have one answer. I also recommend that you consider submitting an Idea in this area:

Speaking purely from my own experience, making the name of the instance admin visible in an instance that could contain upwards of thousands of users, might be "considered useful" to the users but not necessarily beneficial or within the roles of the admin at hand.
Additional: It's a good practice for admins of an instance to at least provide a queue where you can escalate your needs. For example, many admins would provide a request queue where users can request further configuration or need for access.
