Thanks for suggestion, will do it when I'll get some time.

Well, KiCad's VRML2 parser is so fragile that I did not try to squeeze file sizes.
One of the most obvious optimizations would be to use the %g rather than %.6f floating-point format to get rid of those "0.000000" scattered through the output file.

Blender can work with exact coordinates. I just took the vendor PDF file and created a draft given the sizes.
What I like about it is that you can control every vertex of the output.
This helps avoiding generating complex meshes, I don't see much sense in using models like those found on 3dcentral to render the board in KiCad... most of them are overcomplex.

Well, it's pretty easy to create such VRML2 files :)
For example, just remove a single comma from the coordIndex[] array, or place all numbers on a single line, or remove commas from "coord Coordinate {" array etc.
This is still valid VRML2 (commas are optional, numbers can be separated by spaces as well), but KiCad won't accept such a file.
