As I mentioned the last time you asked :), we use blueprints, and the template is here: https://blueprints.launchpad.net/horizon/+spec/template

Please register a blueprint for discussion / tracking. The change looks sensible, although I’d prefer we use a setting name like https://docs.openstack.org/horizon/latest/configuration/settings.html#openstack-keystone-domain-choices. It’s a bit less ambiguous.

Hi, Horizon developers,

In our OpenStack based public cloud(Catalyst Cloud), Keystone is a shared identity service across 3 regions, our customers have been asking for the feature that they could select their preferred region when they log in Horizon, rather than switching region each time after login.

Unfortunately, the existing 'AVAILABLE_REGIONS' only works with multi-keystone, multi-region environment, so for backward compatibility and getting rid of potential confusion, a new config option named 'AVAILABLE_SERVICE_REGIONS' was introduced in my patch[1][2], the setting is supposed to be configured by the cloud operators and the 'AVAILABLE_REGIONS' setting will take precedence over 'AVAILABLE_SERVICE_REGIONS'.

I am sending this email to ask for more feedback, and do I need to propose a feature spec before the code is actually being reviewed?
