Is this possible to do in A17?

My understanding of the size reduction is that RWG will do a more complete pre-generation for A17.

Alpha 16 pre-generates hub cell data and distant terrain. Chunks are physically generated on first visit.
Alpha 17 pre-generates a more complete version of the data. Chunks are generated during pre-generation. This means initially larger save files. Physical visits to a chunk are the same if it is the first or the 50th time since the data is just loaded.

This will result in Alpha 17 RWG map chunks loading during play and while traveling as fast as Navezgane chunks. This should result in less chance of falling through world on vehicles..

To be clear.
Outer Circle = Alpha 16 RWG size. 10k radius circle. 314 square km
Bigger Unfilled Square = Alpha 17 RWG per Developer Diary. 8kx8k square. 64 square km
Smaller Filled Square = Alpha 16 Navezgane. 4kx4k square. 16 square km

Outer Circle = A16 RWG
Inner Square unfilled = A17 RWG
Inner Square Filled = A16 Navezgane
