Description

Background

Context:

The current length of the action_context property is 64 characters, which makes it very difficult to include arbitrary contextual data in analytics events, which we have called "data stuffing". However, there is still a need to do so every now and then. Since we haven't yet provided guidance on how to avoid data stuffing, should we increase the length of the property?
