Why are the `bridge-slave`, `bond-slave` and `team-slave` interface types no longer supported in RHEL 8 and newer versions?

Issue

• Why are the bridge-slave, bond-slave, and team-slave interface types no longer supported in RHEL 8 and newer versions?
• Why does bridge-slave not work with bond or VLAN?
• Unable to bring UP bridge-slave type connection.
• Error: Connection activation failed: No suitable device found for this connection (device enp1s0 not available because profile is not compatible with device (mismatching interface name)).
