Environment.SetEnvironmentVariable: we recommend that the length of value be less than 2048 characters

Description

From https://learn.microsoft.com/en-us/dotnet/api/system.environment.setenvironmentvariable?view=net-10.0#environmentvariabletargetmachine-and-environmentvariabletargetuser-on-windows-systems

If target is EnvironmentVariableTarget.User or EnvironmentVariableTarget.Machine, we recommend that the length of value be less than 2048 characters.

Is this recommendation still up to date?

Why does Microsoft recommend that the value be kept under 2048 characters? What happens if it's over that size?

I tested it (on Windows 11) and it seemed to work for me with a string that e.g. had over 3000 characters. Let me know if you can provide any more context on this, thanks.
