I think you're right on the money with this Dennis. These devices are OK for small lighting loads (i.e Halo recessed cans, etc.). However, IMHO, I wouldn't use them for receptacle or other large draw loads. People have a tendency to see an unused receptacle and assume they can plug 2 electric heaters into them. Don't forget, that first Wago splice is taking the heat for every other connected device down-stream.
Don't forget that if you are supplying a daisy chained group of recessed cans or something similar that you have the same thing. One port is the low current of the luminaire. The other ports - one is carrying all current, the others are carrying current that sums up to whatever total current is.
That is correct but lighting loads are generally not as great as receptacle loads.
Really? You never put near circuit capacity on a circuit with nothing but lighting? Especially in commercial installations?
I generally don't load a circuit beyond 80% of the breaker size but I know it's done. So, I suppose you're right. Sometimes I don't think out of the box. But thinking along those lines, let's say you have a group of 2 x 2 drop in fluorescent fixtures w/ electronic ballasts and (2) U-bent 32 watt bulbs per fixture. Each fixture draws .52 amps. Would you customarily put 30 fixtures on one circuit and draw 15.6 amps on a 20 amp circuit or would you load the circuit to 38 fixtures and draw 19.76 amps ? I'm not trying to pirate this thread away from the OP. I'm just curious to know your thinking on this because I know you love banging heads with me.
The principle is similar but the construction is different. Only the end of the metal used as the spring to create the contact pressure for the connection is used in the push-in receptacles. This spring metal is very thin and there is very little contact area beween the wire and spring. The actual contact area for the electrical connection is opposite the spring.
I see lighting as a continuous load most cases, so 80% will apply. So if you are supplying one chain of luminaires loaded to 15.6 amps the connectors at the first luminaire are carrying 15.6 amps vs the last one that is only carrying .52 amps, that is more current than a backstabbed receptacle with a 1500 watt heater plugged into it has passing through it. (and the heater is true power, the electronic ballasts still have harmonic currents added to the mix)I generally don't load a circuit beyond 80% of the breaker size but I know it's done.

Just curious, would you think these would be an acceptable means of splicing neutrals in a MWBC ?
