Not at all. I find it useful for certain tasks, but I’m a huge introvert and spending a long period of time with someone physically exhausts me to the point where I can’t muster coherent speech or thought. Depending on the depth of thinking required too, it’s often better for me to do that individually then bring my findings to someone else to validate.

I’ve used it with a lot of success at my current and previous companies. To address a few of your cons:

• Engineers are quickly comfortable with the tooling and VS Code plugins give you quick feedback. You can also point the plug in at a hosted instance to avoid running a local instance in Docker

• Separation of different types of diagram is often a bonus—too often have I seen architects try to cover too many concepts in a single diagram—instead a Context diagram should define your system and its neighbours, a Container diagram the major pieces of your system, a Component diagram verges on design and is a good place for engineers and architects to converse. If a container or component has a particularly complex workflow, then a supplementary flow diagram helps. If it uses an extraordinary pattern, then a class diagram might help, and so on.
