my er9 included all imaginable bolt lengths and adaptors for 140 to 160mm discs, something that costs extra and requires significant brain damage on Shimano. I think a very small fraction of the market cares about post mount (at least on the road setups), i wouldn't even want to pay for the shipping cost of bolts of another thread size. Shipping from China is a large portion of the cost of everything we ride in the West.
Can you explain how does adding an extra spacer will resolve the headset play? Also where did you purchase the spacer from?
I'm curious with the hydraulic hoses on fully internal frames. On semi-internal frames you can just detach the stem/bar from the bike and pack the bar sideways next to the frame in a box.
On fully internal frames, is this not an option for travel? Do you have to detach the hoses for travel? Sounds like a big hassle if that's the case.
