Chromium is a well-organized and mature codebase, which makes syncing changes relatively easy (also Brave’s chageset is limited in scope, so less conflicts to worry about). PieFed is neither mature nor well-organized. Maintaining a downstream project from it would be a nightmare.
I think the Brave browser does it with Chrome. Wouldn’t the source control tool do most of the maintenance?
