1. I tried to consult the code-style file while making the changes and made sure that mvn validate is happy, but I might have missed something, pls let me know if I have to make any changes.
2. The changes don't seem to be breaking to me. Please correct me if I'm wrong.

Hello everyone. I am going on vacation until February so I won't be able to react to any responses here. If this PR can wait until then, I will happily finish it in February. If not, I kindly ask @bretg to assign the Issue/PR to someone else, if any changes are required.

@EmilNadimanov is it ready for review?

[EmilNadimanov]

@osulzhenko it is. Am I supposed to mark it with a tag or something like that?

[osulzhenko]

@EmilNadimanov No need—if it doesn't contain "WIP" or "draft," it will be considered ready. I was just confused by the message, which is why I decided to ask. The PR will be reviewed soon.

Also, please, add integration tests for new alias

Thanks for reviewing. I will get to it sooner or later, I am currently quite busy with our internal work. Sorry for that.

[EmilNadimanov]

@CTMBNara I've made the requested changes. Sorry that it took so long.
