# Rationale for this change
<!--
Why are you proposing this change? If this is already explained clearly in
the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand your
changes and offer better suggestions for fixes.
-->
See ticket, but we need to switch to a null buffer representation that can
store its offset separately from the ArrayData it belongs to. There isn't an
obvious way to add support for this without a breaking change. Fortunately most
downstreams are not interacting with the null buffers directly, and so the
impact of this change shouldn't be too problematic.
