I think Alexiev is off to see Santa 'til January .. but
this is a not from a patch he dropped to the CDT mailing list
it should give you a rough idea of his way of thinking.
The part about a default "Main" group is probably CDT specific
and there for backward compatibility.

/**
 * Custom command for requesting the register groups.
 * It is not yet in the GDB stream.
 *
 * -data-list-register-groups
 *
 * The format of the command is:
 *              IN:(gdb)-data-list-register-groups
 *              OUT:^done,register-groups= [{name="r0", group="GRP1"},{name="r8",group="GRP2"}]
 *
 * It is similar of the command: "-data-list-register-values".
 *
 * The register group names are case sensitive.
 *  * The register groups appear in the Register View in order they are returns from
 * the command "-data-list-register-groups".
 *
 * The registers appear in the groups in the order they are returned from the
 * command "-data-list-register-names".
 * The register names are case sensitive.
 *
 * If the debugger doesn<92>t support the command "-data-list-register-groups" all
 * registers are added to the "Main" group.
 * If there is a register returned by the command "-data-list-register-names" but not
 * in the command "-data-list-register-groups" it is added to the "Main" group.
 * The main group itself is added first to the Register view.
 * If there is a register returned by the command "-data-list-register-groups" but not in
 * the command "-data-list-register-names" the register is ignored.
