why just pool MemoryStream

[trivalik]

Wouldn't it make sense to have these kind of library also for other types like List<T>?

There is already not maintained repository https://github.com/jtmueller/Collections.Pooled, but not from Microsoft.

This is a very specialized class for interacting with byte arrays and the special considerations they have related to streams. It is not meant to be a general-purpose pooling mechanism at all.

I know this library is just for memorystreams. I just wonder why this is not bigger over several types. Since the readme tells about a pooling mechanism "the underlying buffers are pooled". I just want awake that this could be possible (maybe in another microsoft project). Feel free to close this issue.
