This is mentioned under every Firefox discussion despite being possibly years away from being generally useful if the will ever progress to that point.

What exactly is Firefox going to do differently to grow its market share? Or just "more of whatever the last fifteen years have been"? Unless they have a plan to do better it seems foolish to trust that they'll steer the project miraculously towards success.
The former. Ladybird is currently not practically usable, it is unclear whether it will ever catch up to the main engines, and even if it does, it is unclear whether it will ever reach the market share that Firefox has. It is a nice project but science fiction at this point.
