allow group terraforming... somehow? Formers are easily the most numerous and most-often selected group. Can you imagine the tedium of selecting 100 of them and manually ordering every one? Pressing "B" 24 times to drill a borehole? Maybe there is a way to issue groups orders to former teams, aka "Group Terraform Here"? Or select a group of formers and make a terraforming order apply to them all? This might be trickier as normally a terraform command is issued at the tile where the former is standing, and a group can contain units from multiple tiles. Might require some checks or even additional grouping options like "Exclude units not in the same tile" and "Exclune non-terraformers".
