E.g. custom container system or custom OS, in which the JVM cannot detect system memory pressure via standard approaches. So these flags are not necessarily intermediate solutions, and they could allow more deployment environments to use AHS.

Could you elaborate the concrete scenario you have in mind? What use case do you have in mind where AHS is not enough, while external heap control is?
