Answer 1

Has there been an official comment on when security patches and bug fixes will no longer be developed for Angular v1.x?

Not until last contributor goes away! Foremost AngularJS is licensed under liberal MIT License and everybody can fork it and modify it endlessly.

For those worrying about "official Google support" - well, between March 2016 and March 2017 there were 20 releases of AngularJS 1.x - the latest is 1.6.3 - doesn't look like abandoned project any time soon. It differs so much from Angular v2 and v4 (to be released this month) that it will have it's own life even after Google decides move away. Either they transfer the github project to community maintainers or community fork will take over.

There are lots of spectacular examples of communities taking over projects for various reasons. A notable example is io.js - large group of contributors decided to fork Node.js when Joyent, the creator company, was not releasing updates often enough to satisfy the community.

This is the beauty of open source software.
