I want Fast-DDS to be successful as I want anything that ships with ROS to be successful. When issues are brought up, they’re not critiques as reasons not to use Fast-DDS, they’re issues that need to be dealt with so that users may effectively use Fast-DDS. At the moment, at least in my niche, Fast-DDS has some serious issues but they are problems I assume can be solved and I have full faith will be solved. I’m simply addressing them so that they may have awareness to be solved.
If anything, now more than ever I want Fast-DDS to be successful and work through these issues because its the default face that users will see out-of-the-box (and I’m sure from our discussions & comments above you recall how much I value that). Just as I’ve been asked in the past to specifically call out other DDS vendors in my documentation as “use this” or “officially supported”, I’ve refused because I’m not pro-DDS_A or anti-DDS_B. I’m pro-things-just-working so I can focus on making the best navigation system around 
But regardless, is this not a channel like any others (GitHub tickets, emails, messenger pigeons, and Discourse)? I think this is as fair of a place for discussion as any.
