Your risk aversion seems justified. It seems reasonable to estimate that very few teams are in the position of needing the kind of scale/scalability that something like Apache Pulsar offers. They are much more likely to be in either a state where they will not put Pulsar through its paces or where they already have a solution in place that serves their scale/scalability needs. When a team you are on starts discussing switching over to a technology like Pulsar because of its amazing benefits, unless your pants are on fire, it is much more likely than not that you do not stand to gain much from the benefits that such software brings but you are accepting the maintenance burden that it represents.
