Ah yes, pipelines do make a difference in configuring jobs. However, how are you managing your plugins? Your Jenkins configs? Most likely those are manual (however if you've found a way that works well, please share). I've also found that for some functionality, I've had to add Groovy into my pipelines. That said, pipelines has made a HUGE difference. I still want to migrate but this fixes a large pain point.
And yes, you do end up needing to use Groovy for anything non-trivial.
