📄 Description

To quote an internal wiki:

It generally provides improved footprint and performance over the
existing default heap for native win32 applications.

It is apparently the default heap on ARM64, and for all UWPs.

This heap has different allocation and compaction characteristics.
I am not sure how it will impact terminal.
