I also share same opinion based on my experience. Events can be modified and deleted but that must be an exceptional situation (GDPR and other compliances, etc.). But even if it's exceptional you have to provide a clear and easy way to do so and that increases complexity of the solution by a lot.

Another thing is strongly consistent models, there may be valid requirements in some problem areas to have a strongly consistent and normalized model and use it for command validation. This helps especially well in the case when all requirements are not known upfront and/or business domain changes very frequently. A small change in business may require to completely redo the aggregate roots and logic if you follow standard approach, this is very expensive. A better decision could be to use a normalized SQL database instead of an aggregate root. Such approach may be more flexible in certain cases and have it's own benefits as well as cost and drawbacks.
