Applies to all rules related to Apex and Visualforce. Back then when I ported PDM to Salesforce CodeClimate was the only platform to integrate with. To make PMD work with them we had to add custom renderers and properties.

Neighter I nor somebody else is using this anymore and it clutters the rule and ruleset code. So I'd suggest we remove this again.

I can provide a PR for that. But I want to hear your opinion on this @jsotuyod @adangel
