[Mesh] Unwrapping.GenerateSecondaryUVSet can fail but the API does not indicate the failure in any way

Mesh

-

How to reproduce:
1. Open project "ok.zip"
2. Open Scene "TestGenerateNewUV2Layout"
3. Press Play

Expected result: Unity handles the abundance of vertices or provides a method to detect the failure of Unwrapping.GenerateSecondaryUVSet();
Actual result: Error: SetPerIndexUVs failed because the output has too many vertices

Reproducible with: 2018.4.30f1, 2019.4.16f1, 2020.1.16f1, 2020.2.0b14, 2021.1.0a8
