Requesting a Read Only permission option for processing rules

It would be very useful to have a "read only" permission for Processing rules.

Currently (according to Customer Care) if someone is given permission for processing rules, that permission includes the ability to add or modify processing rules.

We have staff who need to see how a processing rule is written, but should absolutely not have the ability to add or modify rules (intentionally or accidentally). For example, the QA team who may need to follow the data flow (page > tag manager > Adobe call > processing rule > vista rule> data feed > etl, for example) to identify the cause of some data issue. Or the dev person who is writing code dependent on what the processing rule will or has done and needs to understand that rule.
