Is Azure AD App-Only deprecated

Question

I am following the steps mentioned on this link @ https://learn.microsoft.com/en-us/sharepoint/dev/solution-guidance/security-apponly-azuread to register a new application inside Azure AD. but when i click to register a new application, i got this message:-

so does this mean that Azure AD App-Only is now deprecated ? if the answer is yes then what is the most up to date approach?
now what i am trying to do is to register an application inside Azure AD and create a certificate then use the clientId,TenantId, certificate to be able to authenticate my SharePoint CSOM code against SharePoint online using this code PnP.Framework.AuthenticationManager(clientId, certificatePath, certificatePassword, tenantId);

Hi @john john
You could still use Azure AD APP-Only.

However, take attention: If you choose not to migrate to MSAL before ADAL support ends on June 30, 2022, you put your app's security at risk. Existing apps that use ADAL will continue to work after the end-of-support date, but Microsoft will no longer release security fixes on ADAL.

For more information, you could refer to:
