alt Hacker NewsI think it's a reasonable price to have your own containers (vector/unique_ptr replacements), if you wish to use a non-standard approach for memory allocation. Many people do this, like Qt with QVector.
But do you really need arenas? Does doing allocations in a traditional way creates a bottleneck in your specific use-case? Or you just want to justify broad manual memory management (with its bugs and secure vulnerabilities) in hope to gain (or not) a tiny amount of extra performance?

Isn't using Arena just simplifying memory management, thereby reducing the amount of bugs as well?

Respectfully, you do not seem to understand this topic well. If the C++ standard library design abstracted memory allocation correctly, you’d still be able to use containers and algorithms and not even notice that their allocation strategy uses the heap, stack, a bump allocator, a pool, etc
