Sorry to not reply immediately yoMuzicMan. Yes these have always been just push on knobs and they are a good tight fit. You have to be careful when taking them off that you don't damage the pots as these are not simple easy replacement ones. Most of them are digital pots which are a part of the MIDI setup. You don't want to have to take it in to have one surgically removed from the PCB and replaced.
You should be able to lever the knobs off if you approach it from both sides with duplicate levers and apply pressure evenly. That means the stress on the shaft is kept square up the centre. Sometimes just a couple of sturdy picks will do the job if you use heavier gauge ones. One other way I have seen them removed is to take a piece of strong string or a ribbon material which is not too thin so as to cut into the knob edge and wrap it around the shaft a couple of times under the pot. Position the ends so they come forward on opposite sides of the knob and tie it in a loop a few inches in front of it. Put something strong like a screwdriver through the loop and allow the string to even itself up when you pull. Pull square forwards as before and the knob should pop off. Another way is to get a big pair of pliers, sometimes called water pump pliers, with a wide rounded section in the jaws. Wrap a piece of cloth around the knob a few times then grip the cloth from the side so the pliers fit around it as much as possible. Keeping them square to the shaft, pull the pliers upwards with your other hand to release the knob. There are vids on YT showing these methods if you need them now.
I'm with you on leaving those others alone. That sort of detail is only really obvious when you are inspecting very closely or actually turning the knob so you see it swing. For me it wouldn't be a big issue as I am more interested in the sound I am getting rather than impressing other guitarists with my ultra hip perfect gear.
Of course other people do have different priorities.
