Understandable, though I think this way is significantly simpler, and won't be
much of a perf hit.
We allocate at most 4 elements in the list per resource, never any more for
valid shaders. We would need to allocate at least one subelement with which to
compare other subelements against using your method. It may be slightly less
performant, but I think this is readable and it doesn't drag the performance
down from O(1) to O(N) for valid shaders.(N being number of subelements)
