Saving Metal in the Framehead

Bicycle Repair Man !!!
It is a really bad idea.
Drilling holes in the frame to fit rivnuts and bottle cages is one thing... they do not experience any shearing loads or much load at all.
Using a machine screw to secure the steering assembly on a bicycle might have been tried in antiquity and this is why traditional quill stems have expansion bolts. As non rotating weight, the grams you might save here are pretty much worthless from a performance perspective.
Machinist, frame builder, UBI Certified Technician, and I have been turning wrenches for over 30 years.
Besides that I have a degree in rehabilitation to help deal with folks who Darwin themselves when they experiment with things without understanding basic engineering and physics principles.

Thanks, Sixty Fiver, for the reality check. I had already realized that flaw in my idea.

I want to see the engineers in a no holds barred slide rule death match. No pocket protectors allowed!

Now you're talking about convenience - not necessity. I have a couple bike bags to travel with. Lots of people that use carboard boxes would argue that bike bags aren't a necessity. And they'd be right.

For road biking.. IDK, maybe for really nice places that are very far away you would want to take the train.
Anyway here a typical train has 8 slots/wagon for bikes. The catch is : they are very close to one another where you can barely fit (and overlap) handlebars for road bikes. For full MTB/XC/DH/FR bikes the arangement in the bike rack to fit 8 of them is really a challenge (and may require to fit a couple in reverse).. => simple solution not to disturb anyone, flip the bars in 10 seconds. - convenience and necessity if you want to get your bike in that damn rack.

Not sure what you mean. I was talking about taking the train with your bike as whole not a disassembled one, and not as luggage. Just the average ride with a few friends, take the train to some cool places and carry on on bikes on our beloved route that we chose, then head back the same day with a later train. Very handy for mountain biking when you live in a flat area - take the train to the mountains and unleash yourself .

was referring to above
function v safety
we were both contending that
in terms of safety
it is ok to remove and ride with no top cap or expander
in most carbon steerers
unless otherwise directed by the fork manufacturer
although
there is no good reason to do so
and doing so makes adjustment and assembly a pita
