ALU Packing Window

Are there any plans to improve this window?

For example, the window size is not paritcularly large AND the window doesn't seem to "slide".

Example: If you have a kernel that has 100 instructions with 100% data dependency that arer non-vectorized (only use 1/5 VLIW) and then another 100 the same way but with no data dependency across the two 100 instruction sets you get no packing from compiler.
