I started on upright. My first electric bass teacher was an upright player who taught me to just use upright fingerings lower on the neck. As I go up the neck I start using four fingers once it is comfortable. This was very useful in that I didn't have to re-learn tunes using different fingerings once I started gigging on electric. To this day your can see Geddy Lee, Lee Sklar, and plenty other players using a 1-2-3 or 1-2-4 fingering lower on the neck. Honestly it works fine and has never slowed me down. Brian Bromberg even occasionally drops into doublebass thumb position once he is past the octave/12th fret.
A short clip on Geddy Lee soloing. I don't see him using 4th finger here. He seems OK without it.
Here is bromberg un-apologetically mixing 'regular' fingerings with thumb position. Again, total deviation from "standard" fingering.
I guess my point is that I don't see where it has to be a religion to play one way or the other. For upright players we are happy (and quite nimble btw) using Simandl fingerings similar to what Geddy lee and Brian Bromberg do in the above videos, although I can see how migrating from guitar might make you want to stay with what you know throughout the entire neck. One might argue that you can catch more without shifting using 1-2-3-4 fingerings. THat may be but I have never run into anything I can't handle using fingerings like what you see in the videos here.
Not trashing any particular technique, just advocating for a more flexible approach since that approach obviously works as well.
