### Is the 011 notation for octal 11 deprecated or not?

Hello, Sage Community!

A few months ago, when compiling Sage code to convert the octal 11 to decimal notation, I got a deprecation warning message telling me not to use 011, but 0o11. That was with SageMath 8.x (possibly 8.8 or 8.9; I don't remember exactly).

However, right now (version 9.1), when I run the command 011, it returns 9 (the decimal representation of octal 11), without any deprecation warning.

As the title says: Is the 011 notation for octal 11 deprecated or not?
