System Information
Operating system: Linux-5.11.0-40-generic-x86_64-with-glibc2.31 64 Bits
Graphics card: NVIDIA GeForce RTX 2070 Super/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 495.29.05

Blender Version
Broken: version: 3.1.0 Alpha, branch: master, commit date: 2021-11-26 10:08, hash: dcc500e5a2
Worked: master from a few days ago

Caused by d7cf7d4048.

Short description of error
Linking a Collection (in this super simple case a blend file containing two cubes that are parented to two bones on an Armature) not only links the Collection Instance but also the Collection containing the two cubes.
The file contains that is linked contains this:

LIB_Cubes_v01.blend

Exact steps for others to reproduce the error

Download the attached blend file
Open Blender with an empty scene and link the Collection "Geometry" from this file into it.
It should look like this:
But in current master it looks like this:

As you can see the "Cubes" Collection is linked additionally and has to be unlinked before "Make Library Override" to not clutter your scene with stuff you don't need.

This behaviour is rather new so the only commit I think could've caused it would be this e253fb2143
