Any schedule on when login action stops supporting Azure CLI < 2.69.0?

There are currently no plans to change. Telemetry shows that about 30% of users utilize self-hosted runners, which may not always install the latest Azure CLI. Additionally, all managed identity users are using Azure VMs. So I would like to continue supporting login action across different Azure CLI versions, similar to cli action.

else {
args.push("--client-id", this.loginConfig.servicePrincipalId);
}
await this.callCliLogin(args, 'user-assigned managed identity');
}
