The email inquires about the purpose of wg- tags within a specific context, expressing frustration over the inability to respond to a proposal marked with such a tag without having permission. The sender is seeking clarity on whether these tags are meant to signal that only replies from members of a pre-approved list (allowlisted group members) are accepted. This question stems from an experience where significant time was invested in understanding a proposal, only to find out participation in the discussion was restricted. The sender is contemplating whether to interpret the presence of a wg- tag as an indication to disregard the content to avoid future instances of wasted effort. The goal is to gain a clearer understanding of the tagging system to better navigate which discussions are open for broader engagement and which are closed to a select group of contributors.
