What does the ionic plugin wrapper do?

I just installed ionic v3 (3.19.1). The newer plugin installer is causing me issues.

ie: ionic cordova plugin add ionic cordova plugin add https://github.com/lampaa/com.lampa.startapp.git

Errors out with:

> cordova plugin add https://github.com/lampaa/com.lampa.startapp.git --save
(node:7616) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 1): Failed to fetch plugin https://github.com/lampaa/com.lampa.startapp.git via registry.
Probably this is either a connection problem, or plugin spec is incorrect.
Check your connection and plugin name/version/URL.

However, if I just do the traditional cordova plugin add ... on the same plugin it installs just fine?

If I don’t use the ionic wrapper, does that impact my project at all?

In fact, the wrapper seems inconsistent. On another plugin, I use the ionic cordova plugin add.... and it fails…then I try again and it works.

Regardless of the plugin, when it does error out, the most consistent error I am getting is trying to fetch certain packages using git:

cordova-device-information-plugin
