The thing is, most real-world numbers will fit within 1-3 bytes (even at 7 bits per byte), so ultradense packing doesn't actually buy much outside of benchmarks.

I spent WAYYYYYYYY too much time exploring this...

This is like string functions, there are some variants with just crazy SIMD when the mean string length is ~14-20 bytes
