The ability for us as developers not only be able to use our own SQL but also have access to all Oracle R12 features is amazing! It allows me to write code in C++ with no issues at all. If I need some help writing an ETL process then we can connect using ODBC which will allow my developer colleagues from other teams to understand what's happening under-the-hood when running these processes. There are certain limitations such as DDL commands being disabled by default - this makes sense security wise but could still do better. Give it try if you're looking to move away from vendor lockin. We were locked into one particular version of Microsoft SQLServer (which was great) however wanted greater flexibility over how we used our Data warehouse/ETL functions. This allowed us to build out multiple solutions quickly and easily within our organisation rather than having.
