The hard quota is not my idea. It's what those browsers who do implement
WebSQL implement. Unlike IndexedDB which triggers a "do you want to allow
yadda yadda" or whatever, at least sometimes, WebSQL is hard limited to 5mb.

And as to why large sizes do matter. Let's take the sponza atrium in binary
form including normals, positions, texcoords and material IDs (100mb). If
you chuck out a bunch of things you can compute, structure and otherwise
make smaller, you can get out at some 12mb. But you can't send that to the
GPU. You've got to convert it to something that's usable for the GPU, which
takes up around 1-2 seconds of CPU time in JS if you wrote a
super-optimized piece of code. Now reading 100mb from disk to a binary
representation shouldn't take more than about 80ms or so worst case. So It
would be kind of really desirable to be able to store temporary calculated
assets. Another usecase for large asset storage is productivity software
that deals with images/meshes. The amount of data you quickly generate with
that kind of software is staggering, and in the interest to keep things
easy to use it would be kinda nice to be able to manage assets on the
client other than file drop.
