I don't know if "problematic" is the right word seeing as even with manual memory management you have to do the same techniques. The problem is with allocation/destruction in general within the core loop.

It's more problematic in languages that encourage allocation since you have to work more to avoid it.
I've done game development in C++, C#, and JS, and I had to worry about memory management far more in JS than in C# or C++, simply because even something as innocent as adding two vec3s requires you come up with a space for the result first, if you want to avoid gc hitches.
C#'s struct types help here, but it still has plenty of its features increase GC pressure.
