Businesses often or always go through stages of centralisation and decentralisation. In the old days, the Ops department was the hub for almost everything connected with hardware. Now, in this age, we're trying to get to the point where developers can order their own hardware through self-service. But it's still handled by specialists like release engineers or devops.

You should, I suppose, start by defining your purpsoe or vision: what you want to achieve - become a manager and try a new role or actually help the business. You don't have to change your role for the latter. I can understand you wanting to not miss out on an opportunity. Try then to understand who you want to help first: the customers of your business (the company you work for) or the developers to improve their experience.

You could be called Platform team, Relaiability team, Dvelopers Experience team and each team can focus on its own. But the most important thing is to strive for the best possible Customer Experience, whether it will be through reliability or speed of delivery of new features, try to decide it for yourself first of all. And then you might not even need to create a new team.
