With LEDs becoming so efficient and even batteries getting large capacities. As far as I can tell, the biggest obstacle is heat sinking for these lights. Having a large battery pack or >500 lumen light is for special purposes or situations. You don't even need a dynamo light for longer trips anymore.
Another reason why I shun bicycle specific lights is, they tend to cost more (features, runtimes, brightness, overall quality), ones with built in battery are bigger and bulkier (many with questionable heat sinking), crummy beam profiles, few options in neutral white, very few state ANSI lumens, or IPx waterproof ratings and etc... Oh, and I haven't seen any bicycle specific lights with selft contained battery that have a lock out switch!
