The bug

Versions like 1.18.2 don't support chat signing while newer versions do. These older versions don't support the "latest" player safety features but are not marked as so. I would assume that a version like 1.18 would not be considered to be "as safe" as something like 1.19.3 because players cannot be reported for their messages.

Steps to reproduce

• Open the Minecraft Launcher
• Create an installation for 1.16.3 or below
  → Notice how 1.16.3 has a player safety warning.
• Create an installation for a version following 1.16.3 that doesn't support chat reporting
  → Notice how 1.18.2 does not have a player safety warning despite no support for chat signing or chat reporting.
