subConfiguration "vibe-d:core" "vibe-core"

that currently builds on 0.8.0-beta.3, produces the following in a terminal on Linux x86_64.

../../../.dub/packages/vibe-d-0.8.0-beta.3/vibe-d/core/vibe/internal/memory.d(3,15): Deprecation: module vibe.utils.memory is deprecated - Use the memutils package or std.experimental.allocator instead.

Looking at my own question, probably this just means that vibe.utils.memory is to be replaced by memutils at some point presumably before 0.8.0 is released. Please confirm.
