The only problematic scenario would be a large waveform record where some client solely requests the timestamp.
Always adding the complete waveform would increase the network traffic compared to just the requested timestamp, but I think that's a silly example.

Make that a client that only wants to check the metadata of a huge image (e.g. to decide on the image size if it wants to read the image data itself), and it's not silly anymore.
