We might have been able to do pull requests in Mercurial, but were using a special tool to manage multiple Mercurial repos.

Trunk-based development is where you use a single branch for development, instead of multiple branches that you have to merge between.

Funny, I rarely use branches (or topics) in Mercurial unless it is a complicated long-term project. Modern "everything on a branch" was invented by git users because the UI forces naming things. Mercurial allows sharing code and still linearizing history with rebase safely, so much less need for merges. I've always found pull requests to be only useful for the passing-by contribution. They are a pretty awful interface for anything else driven by GitHub internals more than anything else...
