Thank you for your comment! I understand that there may be cases where One-Shot Bufferize is not yet able to handle, and I appreciate the information on alternatives for the buffer deallocation pass.
Based on this, I will go ahead and close this PR.

Thanks to this comment and I read a comment on this issue. So I think that the name of this pass, convert-bufferization-to-memref, may be misleading. This pass requires that it runs after other bufferization passes, so perhaps it would be more appropriate to rename it or move it to -finalizing-bufferize.
Alternatively, I'm wondering if this conversion pass will eventually be removed, since it is recommended to use One-shot Bufferize instead of Conversion-based Bufferization. I am still trying to understand the details and context of Bufferization. If this PR is not needed, I will close it.
