Thank you for raising this detailed GitHub issue. I am now notifying our internal issue triagers.
Internal Jira reference: https://jira.arm.com/browse/IOTOSM-3790

[LDong-Arm]

The issue is missing declarations of bare-metal support in Mbed OS targets.json. Mbed CLI 1 doesn't enforce profile check whereas Mbed CLI 2 does, which is an improvement.

It's fixed by ARMmbed/mbed-os#14359 after review comments are addressed.
