Replication :: Powershell Not Scripting All Options Specified

I would get from scripting the replication out from SQL Server itself. However, there are a couple of things that are not showing up in the script,Adding the option to IncludeUninstallDistributor or UninstallDistributor doesn't appear to add any code to actually do that. i.e. the below code is never added.

/****** Uninstalling the server as a Distributor. Script Date: 10/1/2015 4:34:13 PM ******/
use master
exec sp_dropdistributor @no_checks = 1, @ignore_distributor = 1
GO
Also, adding the reverse for the create script generation, IncludeInstallDistributor or InstallDistributor, does not add the below code.
use master
exec sp_adddistributor @distributor = N'xxxxxx', @password = N''
GO

The purpose of the script is simply to script out all drop/create scripts for all publications and subscriptions, run the drop script, restore over the databases using backups of non-replicated databases, run the create replication script, and have it re-sync.
