Is there an existing issue for this feature request?

I have searched the existing issues

For shapes, like hollow cubes where a solid area transitions into a hollow wall:

The slicer does not connect the floating solid infill "plate" to the nearby walls:

The extension of each segment would be minimal, but the structural integrity of the print could increase dramatically.

Which printers will be beneficial to this feature?

All

Describe the solution you'd like

Segments should be allowed to be extended into the sparse infill area if it

Does not surpass the "Segment extension limit" set either by an absolute length or a percentage.
If the extended segment will connect to a wall.

Describe alternatives you've considered

Alternative solution would be an automatic"100% infill" within the layer, but not by sum volume, as the current implementation but the local dimensions of the patch (width, length, etc...)
This one needs a more complex algorithm to discover which areas are considered "valid", how to discover thin but long areas, etc...
