The infix modifier documentation discrepancy

[timaliberdov]

The docs say that deprecation will be enabled in Scala 3.1 onwards without -source:future flag:

To smooth migration to Scala 3.0, alphanumeric operators will only be deprecated from Scala 3.1 onwards, or if the -source future option is given in Dotty/Scala 3.

But it seems like the flag is still required in Scala 3.1.2, along with -deprecation for the compiler to emit a warning.
Are there any plans to enable this deprecation of alphanumeric operators? Either way I think it would be nice to edit the documentation a bit to avoid misunderstandings.
