Firebase Analysis and Crash Permissions

Question

I used

//Analytics
compile 'com.google.firebase:firebase-core:9.2.1'
// Crash
compile 'com.google.firebase:firebase-crash:9.2.1'

and got these guys in my generated manifest:

<!-- Required permission for App measurement to run. -->
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<!-- Optional permission for App measurement to run. -->
<uses-permission android:name="android.permission.WAKE_LOCK" />
<uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" />

Then we have the following block

<permission
    android:name="my.package.name.permission.C2D_MESSAGE"
    android:protectionLevel="signature" />
<uses-permission android:name="my.package.name.permission.C2D_MESSAGE" />

My questions:

If I use only Firebase Analytics and Crash and don't need any messaging features, is it good to remove the second block as follows:

<uses-permission android:name="my.package.name.permission.C2D_MESSAGE" tools:node="remove" />

What does “Optional permission to measure the application to run” mean in the first block? Is it safe to remove?
