What's wrong with processors?

[Fernnn]

ServiceNow doesn't want people making new sys_processor items. I understand that they can be problematic, but so can the proposed replacement (scripted REST APIs, which are just an extension of processors BTW). They provide a simple and efficient way to do things that REST APIs do not (e.g. a vanity URL that takes you to a page who's URL may change over time, or based on server processing triggered by parameters in the URL). It may be possible to do that with a scripted REST API, but even if so, it just seems kinda dumb and clunky.

ServiceNow is still creating processors to this day.

I see a lot of vague statements telling us not to use them, but I have yet to dig up a detailed explanation as to why.

This is not a "how" question. It's a "why" question.

Hi @Fernnn 

As per ServiceNow  (Refer: Processors )

Key Reasons to Avoid Deprecated Features:

• No Further Updates or Fixes: Once a feature is deprecated, it will not receive enhancements, security patches, or bug fixes, leaving your instance vulnerable or out of date.
• Support Ends: ServiceNow Technical Support will no longer assist with issues related to these features.
• Upgrades and Risks: While deprecated features usually remain active in your instance after an upgrade, they are considered custom code and can break or cause issues with newer releases.
• Performance Issues: Old technologies  may not be optimized for modern performance standards, potentially causing slowness.

This is exactly the sort of vague and unhelpful answer I called out in my post. Most of these points don't even apply to processors specifically, given that they are an essential part of the platform.

Hi @Fernnn 

If we continue to rely on a deprecated feature and choose not to adopt the modern capabilities provided by ServiceNow, it may become difficult to fully appreciate or accept the rationale behind the proposed changes. In that case, even well-explained and logical points might seem unclear or less convincing.
