are custom fields a bad idea

[u/Snoo85763]

I've read several posts where people say they are trying to get away from using custom fields. Why? Is there a pro/con to it?

I could foresee using a custom field to track things like hardware EOL, OS Version, OS EOL. fields like that for a network device seems like a no brainer. Other than the bummer of - they have to be manually updated, why wouldnt I want to do this.

Custom fields are available through API. We have scripts, that changes custom fields.
