Pacman provider shouldn't be doing partial upgrades

Puppet Version: 6.10.1
Puppet Server Version:
OS Name/Version: Arch Linux

Every time the pacman provider is used to install a package, it includes the y flag to refresh the package list, eg:

==> default: Debug: Executing: '/usr/bin/pacman --noconfirm --needed --noprogressbar -Sy virtualbox-guest-utils'

From the Arch Linux wiki, this is a "partial upgrade" which they say shouldn't be done:

https://wiki.archlinux.org/index.php/System_maintenance#Partial_upgrades_are_unsupported

Desired Behavior:

Either:

1. Don't refresh the package list (remove the y flag), in which case new packages will be installed matching the same point in time version as the rest of the system
2. Add the u flag so the package list is updated and all existing packages are upgraded to the current point in time versions

Option 2 probably isn't desired( ? ). Asking Puppet to install a new package shouldn't result in the rest of the system being upgraded( ? )

Actual Behavior:

Running on Arch Linux (with pacman as the default provider), this resource:

{package { 'virtualbox-guest-utils': ensure => 'present' }}

should produce something more like this in the log:

 ==> default: Debug: Executing: '/usr/bin/pacman --noconfirm --needed --noprogressbar -S virtualbox-guest-utils'
