[Feature Request] Let us create public groups without setting a public username

We all know that a single telegram account can produce 10 public groups: that's because telegram lets you use up to 10 public usernames. But recently it changed.

If you link a channel to a private group, that group will be "public" and it can be linked with its id (for example, see photo https://imgur.com/7Wb0Vzr )

So here comes my feature request: when setting a group and choosing between private and public, let us choose another option, "semi-public", where the group can be reached by its id, but not by telegram global search. That way, telegram admins of large communities of groups can finally be sure that their links won't expire.

What do you think?
