Is the goal for all wg- tags to indicate that a topic only accepts replies from allowlisted group members?

I just spent a bunch of time trying to understand a proposal tagged with a wg- and am frustrated that I can’t reply unless I beg someone for permission. I want to avoid wasting my time in the future, so I want to know if I should just read wg- tagged stuff as “Ignore this for now”.

To be clear, I appreciate the idea of small group discussions being publicly archived for posterity. Thank you to @ajtowns for setting that up and to everyone who is using that feature. I just don’t want to read stuff until I can do something with it.
