Being a generalist in many areas doesn't preclude you being an expert in one, like T-SQL.
I advertise myself as a production DBA. I can sit around and write T-SQL SP's day in and out that work. I don't enjoy it. I can look at a SQL Server, figure out what the internal bottlenecks are. I can also figure out where the network routing issues are or build a server from bare metal.
I can also do it with Oracle, but that is a few years old.
When you say SQL to me, I ask questions of what chunks you need help with. I don't commit on you need a prod DBA but want a developer.

A little bit of this and a little byte of that can cause bloatware.
