Historically the variable length encoding used a fixed block size of 32
bytes, this made it very expensive for encoding small byte arrays. This meant
we couldn't use it directly for encoding list elements, and instead came up
with an alternative encoding. Unfortunately this encoding is incorrect #5807
Fortunately following #4818 the space overheads for small values using the
variable length encoding is significantly reduced, and so we can just use it
directly. The result is not only correct, but also typically smaller.
