One very important piece of information is missing. If you delete your live.com alias, you CANNOT BRING IT BACK!
Think about it. What good is a live.com e-mail address if it cannot send or receive e-mails? For all intents and purposes, it is the equivalent of deleting your account without deleting it. Also very difficult to comprehend why I cannot delete the live.com address and keep the hotmaill.com one.. Essentially, the Microsoft e-mail systems seem to be a pool of aliases that are internally and inextricably linked to one another. And, I bet 95% of the users are unaware of this.
I will try to provide feedback at the link you provided. My comments are directed to Microsoft, I hope you do not take anything personally. I appreciate every reply I get from the moderators and other users.
Many, many users have been burned by this immediate and permanent deletion of an alias. You should have seen the warning in the image below.
The other way to close a Microsoft email account is to close the Microsoft account (account.microsoft.com) which can be reversed by signing-in to the account again within 60 days.

Microsoft has almost certainly received a lot of feedback about this deleted alias problem but add yours to those already submitted. Another complaint about this won't hurt.
Also... In another post you wrote
"Can someone help me delete my live.com e-mail account but keep my hotmail.com account?"
You haven't closed this email account. You deleted the @live.com address. You can still login to the account with the (now the primary alias) hotmail or outlook.com address.
