PowerShell v5 session history

Session history (with e.g. Get-History) is separately handled from PSReadLine history, accessed with arrow keys. PSReadLine history is saved here and seems to never be emptied:

%userprofile%\AppData\Roaming\Microsoft\Windows\PowerShell\PSReadline\ConsoleHost_history.txt

PSReadLine history can be retrieved using:

[Microsoft.PowerShell.PSConsoleReadLine]::GetHistoryItems()

Curious where this is under Core on Linux. context/todo/research
