To limit the scope, and type of applications people should use Lambda for and Lambda is best at running them.

15 mins max runtime simplifies the resource management and avoid abuse. If you have workload for long running jobs, then that should go to something like AWS EKS/Batch/SageMaker.

That being said, things can change, if more and more people requires long running capacity for Lambda (though I am skeptical of that, as Lambda abstracts the underlying hardware away and is supposedly flexible to the requirements)
