Banks and governments could get trapped into this because a third party vendor implements a system for them that includes this.
Like Salesforce’s “Lightning Experience sites” only supports the latest versions of iOS and Android, as well as only supporting chromium based browsers and Firefox.
A lot of banks and government services run on that platform, and not all of them are going to be smart enough to pay for a custom solution that increases device support.
Salesforce dictates what they support now, not on what people want. If an entity implements it, they can use the put of the box functionality or pay to have it customized to increase accessibility, security and support.
