Is it a bad idea to export action communities?

I'm a small transit operator. I just set up communities, informational and action. On ingress, I strip any existing informational communities with my AS and apply my own. On egress, I apply the actions associated with the action communities.

My question is: should I be stripping action communities on egress (after I apply the actions)?

I asked around a bit and was told "yes" but not given a reason other than "security through obscurity". But I'm going to publish these communities publicly anyway, so I don't really think that makes sense.
