I think we should change this error message to:
Previous usage of '-version {0}' is not supported. '-version' currently only supports returning the current PowerShell version.

I think we should currently error if any value is passed to -v

Now we write the error and then show current version.
Please clarify your request.

Aren't you only writing error if -v 2? Should also error if -v 3

I agree. Will add the error for -v 3 too.

We should error on any value passed to -v. In some future time if we decide to support launching different installed versions of PSCore6, we can decide if we want to overload -v or even introduce a new parameter.

Currently we ignore all values after -v. The docs says the same: accept only 2.0 or 3.0. If anybody use the parameter the breaking change is related only to 2.0 or 3.0 values - we should write an error for the cases only.

Could you comment #4836 - I am ready to implement enumeration of installed versioms.

If we currently ignore all values after -v, then it seems logical to write error on any value passed to -v saying that parameter doesn't have any effect.
Having a parameter that quietly does nothing doesn't look good.

It is an enhancement. It make sense. Thanks!
Done.

I think we should error on any value passed to -v as part of this PR.
Fix #4834
