I wonder if any company is making such pressed together camshafts for old
engines like 350 Chevy and 302 Ford? Lighter weight = less rotational inertia.
Should result in less stress on the timing chain and sprocket.

I must add, that lately we're considering making the camshafts this way:

This would eliminate the roughing process at all.
