Publish-Module can't overwrite - nuget can

Expected Behavior

Overwriting modules should be possible - without bumping version number.

Current Behavior

I'm developing PowerShell modules, and I have two nuget repositories, one for snapshots (modules under development) and another one for releases (production ready modules). I'm using Artifactory as an artifact management system, and I've set up both repositories as nuget feeds in there.

First time I publish a module with PowerShellGet, it works. If I run the Publish-Module command again right after, it fails because it won't allow me to overwrite (the user psmodulewriter has permission to overwrite):

PS C:\> Publish-Module -Path 'C:\Workspace\code\UtilsModule' -Repository 'PSSnapshots' -NuGetApiKey 'psmodulewriter:password' -Credential 'psmodulewriter' -Force
PS C:\> Publish-Module -Path 'C:\Workspace\code\UtilsModule' -Repository 'PSSnapshots' -NuGetApiKey 'psmodulewriter:password' -Credential 'psmodulewriter' -Force
Publish-Module : The module 'UtilsModule' with version '0.0.1' cannot be published as the current version '0.0.1' is already available in the repository 'https://xxxx.jfrog.io/xxxxartifactory/api/nuget/xxxxPowerShellRepo-Snapshots/'.

+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : InvalidOperation: (:) [Publish-Module], InvalidOperationException
    + FullyQualifiedErrorId : ModuleVersionIsAlreadyAvailableInTheGallery,Publish-Module

Possible Solution

A possible solution would be to use the -Force parameter in line 1257 on the master branch in PowerShellGet/PSModule.psm1 like so:

if(-not $Force -and ($currentPSGetItemInfo.Version -eq $moduleInfo.Version))

Context

I'm using a CI/CD process and would like to test the modules I'm developing through the pipeline often, without bumping the version number every time.

This is possible using nuget. If I download the .nupkg from Artifactory and push it with nuget, it overwrites the file without any problem:

PS C:\> nuget push C:\temp\UtilsModule.0.0.1.nupkg -Source PSSnapshots
Pushing UtilsModule.0.0.1.nupkg to 'https://xxxx.jfrog.io/xxxx/api/nuget/xxxxPowerShellRepo-Snapshots'...
  PUT https://xxxx.jfrog.io/xxxx/api/nuget/xxxxPowerShellRepo-Snapshots/
  Created https://xxxx.jfrog.io/xxxx/api/nuget/xxxxPowerShellRepo-Snapshots/ 751ms
Your package was pushed.

Beginnen Sie in PowerShellGet/PSModule.psm1 ungefähr bei Zeile 1257 und verfolgen Sie die Prüfung der Versionsverfügbarkeit und die Behandlung von -Force durch Publish-Module. Reproduzieren Sie das Verhalten mit den beiden identischen Publish-Module-Befehlen gegen den PSSnapshots-Feed und überprüfen Sie anschließend, dass ein Überschreiben mit -Force zulässig ist, ohne die Modulversion zu ändern.
