The biggest problem is you are missing an ecosystem. If someone wants to use it they need to do everything your way. But when using a boilerplate like from laravel, django, ror etc. there is a huuuge ecosystem which can be used too. So many functionality which does not need to be reimplemented. So in my opinion all these one-off boilerplates not build on a well-known framework are too much hustle.
