Is it possible to break the package into multiple parts, perhaps like a bundle? Then you could only load the parts that you need at any particular time.
It could be done, but the question is, what if one of the packages in the bundle depends on all of the rest? And the bigger question is, why lazy loading is not efficient when it comes to many small functions?
Lazy loading just converts an object into a small instruction to load the object. If the object was already small, there's no advantage to that. It's mainly designed to avoid memory use (some rarely used objects can be gigantic).
From a design point of view the reason is that this isn't the problem lazyloading is trying to solve. We didn't have a problem with packages that have huge number of small objects, but we did have a problem with packages that had a moderate number of moderately large objects.
In addition, trying to optimize performance is not usually a good idea unless you can measure the performance of different implementations on real applications, and we didn't have applications like that.
