Completely depends on how often you need to write boilerplate code, and how error-prone it is.

After writing hundreds of instances of ‘fetch this from the server and show an error if it doesn’t work’, I finally wrote a helper for that. It took 2 hours, shouts at me if I use it wrong, and instantly makes my classes easier to read because all the boilerplate is gone. As an added bonus, the invocation is so small that Copilot can write it error-free, which it couldn’t before.

So fetching things is now a thing of a few seconds instead of one minute with a chance of making a mistake. I say it’s worth it.

DRY, but also pre-optimization and dependency hell are bad.
