This is no longer the case: acctest.ErrorCheck should take the corresponding names.<Service>ServiceID, which is generated. It may still be needed in some cases, such as acctest.PreCheckPartitionHasService

Thanks for the clarification. I'll fix the syntax in the acceptance testing ErrorCheck section below.

Given skaff outputs acceptance tests that use the acctest.PreCheckPartitionHasService PreCheck, and most existing services use it, I think this section may be worth keeping.
