Need of dev-python/ecdsa as dependency for cloud component

[zen2]

I've updated my domotic box with homeassistant version 111.0 this week end and I got two notifications telling me that cloud and default_config component was not properly loaded.
In log I got:

2020-06-16 15:24:57 ERROR (MainThread) [homeassistant.setup] Setup failed for cloud: Unable to import component: No module named 'ecdsa'
2020-06-16 15:25:04 ERROR (MainThread) [homeassistant.setup] Unable to set up dependencies of default_config. Setup failed for dependencies: cloud
2020-06-16 15:25:04 ERROR (MainThread) [homeassistant.setup] Setup failed for default_config: Could not set up all dependencies.

So I installed dev-python/ecdsa then restart homeassistant and the problem is solved.
Note: I don't use cloud component.
