Proposal: Revise Rationale of Buffer:

Here's a possible text for the revised Rationale:

As a programmer, if your usage complies with the restrictions of BUFFER: (in particular, no adjacent initialized data that you want to treat as contiguous with the BUFFER: data), use BUFFER: instead of CREATE ALLOT, for image size reduction on some systems.

As a system implementor, you can put the BUFFER: data in uninitialized memory.
