I'd love to see a lossless recording format for Logic Pro such as WavePack or adding ALAC (if it supported 32-bit float with RIFF chunks for bext added for BWF timestamping were added).
Terabytes of data are wasted on dead space on large projects like film and TV work. Stems deliveries can be ~90% empty. CPU's and storage are powerful enough to handle these tasks now. It would make archival so much easier too.
