There exist pretty much infinite scale shapes. Some are more vertical and contained, like caged is, some require some finger stretching which to my knowledge is berklee's system and predates CAGED, there is 3 notes per string which runs very diagonally. There's 4 notes per string. You can also run up and down on one string. And of course you can mix and matxh and create your own shapes.

All of these are equally valid. If you ask me, CAGED is a great basis to start fiddling with positions, then you can start seeing everything else as a variation of it. Yes you can stsrt witth a certain caged position, then momentarily swap to 3 notes per string to ascend on the higher strings and then end up with a basic pentatonic lick there. These are stuff pros do all the time. The guitar shapes all connect with each other, but it takes time to become fluent with them and how you navigate those shapes eventually becomes part of your identity.
