What would be the correct TargetProfile for Ubuntu 20.04 runnin PSCore 7.1.3?

Reading the UseCompatibleCommands documentation, it says the TargetProfiles should follow the syntax:

<os-name>_<os-arch>_<os-version>_<ps-version>_<ps-arch>_<dotnet-version>_<dotnet-edition>

But it falls short on explaining how to get these values.

So, after a little bit of detective work and figuring out which framework version each PowerShell ships with, I come up with the following string:

ubuntu_x64_20.04_7.1.3_x64_5.0.220.61302_core

The most painful to figure out is the 5.0.220.61302 part which I assume is the dotnet-version PowerShell 7.1.3 ships with. Or does it matter?

Especially figuring out the build number is painful because the documentation on the referenced page don't go to explain if 5.0.2 is good enough or should I use the full version 5.0.220.61302.

It's not at all helpful that if I put 'dos_arm_6.1_9.9.9_x64_9999999999_goosfraba' into TargetProfiles, the Invoke-ScriptAnalyzer just merrily goes forward as if nothing happened.

1. Is ubuntu_x64_20.04_7.1.3_x64_5.0.220.61302_core good for PSCore 7.1.3 running under Ubuntu 20.04?
2. Could you update the docs when new version of PowerShell is released? It could prove useful if my case was already in the docs so I could just copy/paste it.
3. Would it at all be possible if Invoke-ScriptAnalyzer would produce at least a warning message when a profile string like 'dos_arm_6.1_9.9.9_x64_9999999999_goosfraba' is passed to it?

Yes, the documentation says I could use PSCompatibilityCollector but when I go there, there's 0 documentation.

RuleDocumentation/UseCompatibleCommands.md と、そこで参照されている PSCompatibilityCollector のドキュメントから始めます。Ubuntu と PowerShell の例について、TargetProfiles の構文とバージョン要件を確認し、その後、値をドキュメント化して、無効なプロファイルが拒否されるのか無視されるのかを明確にします。ドキュメントが例の質問に回答し、不正な形式のプロファイルに対する動作を説明できれば完了です。
