How to name internal roles?

[ericzolf]

On roles that we don't expect users to run. Should we prefix those role names with '__' like we do with internal variables that aren't exposed
I don't think you can do that in Automation Hub. The system roles team had to use a prefix like "private_…” (and document!). zzz_private_?
I’ve seen “0_prep”, “pre_”, “setup_”
