Is there any way you could drain at the lower hose but not have to actually pull the hose off the metal pipe? Almost like using a sleeve similar to what people use for a water temp gauge.
Definitely possible but probably not worth the cost/effort to procure and install. Plus it adds three more places for a potential leak. I think for the frequency of coolant changes (every 2 years or so) either the petcock or radiator hose removal (and associated mess) is tolerable.
I recently did a cooling system rebuild on our BMW and was pleasantly surprised on how easy those hoses were to remove and install. For those that haven't worked with them there's a metal clip that you release with a screwdriver and off it comes. No hose clamps, no twisting, no cutting, no guesswork on hose clamp tension.

Most modern cars are using this system now, in particular on intercoolers etc. The problem is when the 'O' ring inside fails you have to buy the whole pipe!
I'll have to use a pick on the hose and the garbage bag in the bucket method. Thanks @george_tlc and @NLXTACY
You guys are pros at the game for us newer guys.
But with some sort of threaded drain plug?
