I wouldn't trust any holder that didn't have a securing pin/bolt but that's just me.
How can the first point be a plus for swapping cartridges?
Change of cartridge obviously means removing cartridges, mounting different cartridges and aligning in all cases.
Suppose the pad height doesn't have to change (as I found out for my canyon last night when swapping in Boras for Zipps) ... then if you haven't changed cartridge there is no adjusting to be done.
And even if the height does have to change, loosening and tightening an allen bolt is surely easier than the removal, mounting and aligning different cartridges.
The one argument I can see in favour of changing cartridges is the one Geoff raises - where the pad is tricky to get in or out of the cartridge.
On the second point, I much prefer a bolt too but for ease of changing pads. If you mean safety then that is just you as there are tens (hundreds?) of thousands of such holders being used daily without incident.
