Letter of the rule, or spirit of the rule...
In my opinion that's a drained ball unless the player wants to take the tilt chance on nudging it back in.
The way I see to judge a stuck ball, is that in an ideal world all that we want to do is dislodge the ball where it lies, and allow it to take its natural course. Now, even a stuck ball freed up that is dead, center going SDTM, there is still a chance for a player to take a tilt warning or two (on most games) and save that ball. Because realistically 99.9% of all games out there, there is nowhere that the ball can get stuck above the flippers, that a 'dislodge' would instantly doom the ball, like it would here or in any other case where a ball is stuck while draining.
The fact that we put the ball back in the shooter lane is not because it's any fairer - it's not - but is a simple practical fact of life. Judges have to take off the glass and put the glass back on while resolving this situation. There's no other consistent way to achieve this while just 'dislodging' the ball unless people are playing without glass on. The shooter lane is chosen instead of trapped on a flipper (if at all possible) because it's less advantageous to have to re-plunge than it is to have a free, trapped up ball - very slightly.
Arguing that this ball should go back in the shooter lane, or some other outcome other than draining it, or allowing the player to risk their neck on a mega-nudge, at least in my eyes is a decision based solely off of the letter of the rule with a view to gaining an advantage, and with no consideration as to the spirit of the rule and how it came about.
That being said, I remember having a stuck ball resolved with a strong magnet through the glass. Glass taken off, ball dislodged, ball stuck to glass by magnet, glass reinstalled and lockbar reinstalled, and the magnet whipped away at the count of three with the ball as close to where it was stuck as possible. That's the ideal and in this case, would be a neat way to solve it - have the ball 'reset' about an inch about that rubber. Player still has to make a nudge to get it back but it's no longer nearly impossible, and it's not TOO much of a freebie. This is of course, a non-starter for games with non-magnetic pinballs.
