I just did a mini-ablation study for this (prefix sum). By getting rid of the cross-block carry (16 values), you can increase perf from 19.85 to 23.45 GB/s: the gain is modest as most performance is lost on accumulator carry within the block.
An absolute value every 16 deltas would undermine compression: a greater interval would lose even the modest performance gain, while a smaller interval would completely lose the compressibility benefits of delta coding.
It's a different matter, although there is definitely plausible motivation for absolute values every X deltas: query/update locality (mini-partition-level). You wouldn't want to transcode a huge number of values to access/modify a small subset.
