There was a problem hiding this comment.
Neither the old nor the new wording applies to Windows (since #849, because rootfs is not a GUID path). I address that in the in-flight #838, and am leaving it alone here since it seems orthogonal to dropping “consider”. If folks do want me to address the “does not apply to Windows” issue in this PR as well, I'm happy to pull over some of the #838 wording to do that.
SHOULD means that [1]: ... there may exist valid reasons in particular circumstances to ignore a particular item, but the full implications must be understood and carefully weighed before choosing a different course. So consideration is already baked into the definition, and we can just say "SHOULD be" and warn folks whenever they use a value other than 'rootfs'. Also move this under the non-Windows conditions, because the advice they doesn't apply to Windows where the value MUST be a volume GUID path (since 2283e63, Windows: Remove Sandbox, additional tweaks, 2017-05-23, opencontainers#849).

SHOULD means:
So consideration is already baked into the definition, and we can just say “SHOULD be” and warn folks whenever they use a value other than
rootfs.Also break this into its own paragraph, because the value recommendation is orthogonal to and less important than the value semantics covered in the preceding sentences.
