What speaks against using a PowerShell PSDrive for SFTP?

When searching for SFTP in PowerShell I find Posh-SSH and WinSCP (see https://stackoverflow.com/questions/38732025/upload-file-to-sftp-using-powershell). Surely working solutions. But when I started looking for SFTP in PowerShell I expected to find a PSDrive. Is the concept of PSDrives not fitting or what might be the reason there is no SFPT-PSDrive? There must be a reason why WinSCP and Posh-SSH took an other approach.
