There is no value to doing ground pours if all you are doing is filling in
unused space on a layer. There are a number of potential problems that
might be created.

Subject: [SI-LIST] Gnd pours
Hello all,
What are your views on gnd pours in multi-layered PCBs (even on top/bottom),
assuming everything is stitched to lamda/8 or /10 etc.
I think it's better to have it as it would reduce the amount of etching the
PCB fab, and thus I'll get a board closer to what my given stackup.
Furthermore, in most cases the PCB adds copper balancing should I not add
the pours.
I understand there could be risks of creating patch antennas, but would this
not be mitigated with stitching?
Kind regards,
--
