My suggestion is to merge PowerShell-core to PowerShell-6.0. In the official repository, both names are being used interchangeably, in the reference documentation, Powershell 6 seems to be the preferred variant.
In my opinion, we should just delete
PowerShell-Core, and keep it
PowerShell-6.0 which matches
PowerShell-5.0. This would match tags like Visual Studio, C# (at SO), Office, Windows. We can use a tag description within 6.0/6.1 to indicate it's also called
PowerShell Core 6.x.
In any event, only a single question has used the tags in question, so we could simply edit that single question and remove the erroneous tag that was created.
We could then make
PowerShell Core 6.x a synonym with
PowerShell-6.0, although the same would have to be done with
PowerShell Core 6.x, so I think simply removing
PowerShell Core 6.0 might be the better option.
A tag merger seems a little overkill for a tag that has been used once.
PowerShell-6.0is the tag that has had a description written for it, a single person, erroneously created the
PowerShell Core 6.0 tag. It has no description currently.
