I believe you mean DDS here, wouldn't the new zenoh integration hopefully solve this? I have heard good things about it and I used it for a project (just zenoh w/o ROS) and I loved it.

There are always tradoffs, people will complaing about the new ROS alternative and create yet another alternative

I think some poeple forget that ROS is written by a very talented roboticists (a lot with PhDs) who did robotics for long time.

Similar to Bjarne Stroustrup's quote on programming languages. There are only two kinds of robotics frameworks: the ones people complain about and the ones nobody uses :D

I had a few conversations with people who complained about ROS and was looking for alternatives (especially lately with more ML people doing robotics with robot learning), imo, it's mostly due to learning curve + doing things the ROS way.

Please add me! I don't tweet much, but I do robotics :D:D
