A whole lot of assumptions in this. Unlike WoW, FFXIV is multi-platform and the development team has made it clear over the years that game balance is very important to them.
Again, there's already precedent for them making an adjustments to a system based on how they saw PC players being able to quickly utilize it in a way that console players were not able to on streams, like they did with Waymark system. However, afaik, this change didn't involve any bans. They made adjustments to the in game system to give Console players access to features PC players were using. They made it so marks couldn't be adjusted mid-battle, added more marks that could be used in later phases if necessary, and added save slots for mark layouts.
If this UI thing is problematic in some way, such as giving PC players access to more information that would normally be obfuscated by default, and enough ppl are being blatant about it... then it is likely that the development team will do something about. However, that doesn't necessarily mean bans, it could also mean giving in and adjusting the UI/tools in game to even the playing field for console players and pc players that don't use mods.
