I think the idea is good, but ideally if feature development is expected to span more than a single quarter it would be best to target phased incorporation into mainline, and not defer everything to the final moment. I think it also helps focus review, testing, documentation etc. to have manageable chunks of work merged long before any perceived deadline.
The way I read this - feature split into few phases. Feature branch that is merged at the end of a phase. Sounds reasonable to me. Incremental work is always preferable, easier to maintain.
