First off, I am aware that many questions have been asked about VCS as a solo developer, but they are often too broad. This concerns only branching. Edit: and still it has been marked as a duplicate...the supposed duplicate is, again, marked as another duplicate of another question that is too broad and doesn't concern branching specifically. That's how my question's unique.

What are the advantages, if any, of using branching as a solo developer? I've often seen it recommended even in a solo-dev context, but as far as I can see, beyond using a 'master' trunk for development, and branching off for working, release-ready code, I don't see how I could harness the power of branching (for example, to compartmentalize new features) without over-complicating the whole development process.
