You're correct that it's a service extending another service; tbh I missed
that too (I'm not the author of the `.thrift` files. I'm also generally new to
thrift so still sorting out what should be generated).
So basically the logic would be to only add `c: thrift.TClient` to the
`*Client` struct if `extends.empty()` in the generator? I'll take a look and
see how hard that looks.---
