Anti-Warping slicing strategy (from Welding)
To prevent warping of the metal in welding, the bead is not run continuously in one line. A small bead is run, and then the welder lifts the stick and goes backwards and runs another small section. I wonder if such a slicing strategy implemented in the slicer could prevent alot of the warping issues seen in 3D printing. The picture below illustrates the back stepping strategy.
The slicer could provide the option to set the maximum continuous length of a printed segment, before it back steps. Could also give the option to skip segments, so there is a gap between segments, that get filled after the layer is completed. The outer most walls would of coarse be printed as one continuous line for quality.
Solid infill would also run similar strategy.

Hi. This is a user to user forum. If you want to make this suggestion officially to the powers that be then it needs to be on the Prusa Slicer github. That is located here https://github.com/prusa3d/PrusaSlicer/issues
It sounds like a similar proposal to this one though in general https://github.com/prusa3d/PrusaSlicer/issues/12119
RE: Anti-Warping slicing strategy (from Welding)
Nonetheless this forum is a much better place to discuss this than GIT because here is where people from many disciplines hang out and may bring in their experience in similar fields. When we conclude here there may be merit in the approach proposed and it comes to proposing an implementation, yes, then it is time to move to GIT.
I like this idea. I have been thinking in similar lines for a while and as it happens I stumble upon this looking for a way in PrusaSlicer to specify reverse print paths, say layers alternatively clockwise and counterclockwise, with an aim to reduce warping and reduce distortion in general.
Alternative solutions I (Naval Architect/Structural Engineer by trade) was thinking of is intermittent deposit, say making 2 passes depositing only 50% of length. Yes, like the method @Tony proposes this requires extra time and it gives extra stop-start defects, but there are cases in which I will be happy to accept those in return for less warping= more reliable and accurate prints.
