Is it possible to add onUploadCallback for InterleavedBufferAttribute?

BufferAttribute have onUploadCallback, why not InterleavedBufferAttribute?
I need to release memory after InterleavedBufferAttribute uploaded to GPU.

Can’t you just use the onUploadCallback() of the respective InterleavedBuffer instead?

I didn’t notice InterleavedBuffer have onUploadCallback, it’s missing in the document and typescript types. I find it in the source code and have tested ok.

thank you!
