Allocation leak warnings are thrown when in Play Mode with Netcode package imported
How to reproduce:
1. Create a new project
2. Import the NetCode package from the Package Manager (or add "com.unity.netcode": "0.5.0-preview.5" in manifest.json)
3. Enter Play Mode
Expected result: Play Mode is entered and no warnings occur
Actual result: warnings are constantly thrown: 'Internal: deleting an allocation that is older than its permitted lifetime of 4 frames'; 'Internal: JobTempAlloc has allocations that are more than 4 frames old - this is not allowed and likely a leak'
Reproducible with: 2019.4.16f1 (0.0.1-preview.6, 0.2.0-preview.5), 2020.1.16f1, 2020.2.0b13, 2021.1.0a9 (0.5.0-preview.5)
Could not test with: 2018.4.30f1 (package not compatible)

I think not printing these warnings in release builds would be a reasonable. Right now it just tanks performance for no reason by logging these false positives.
