Really it's just aesthetics that can be worked around by mapmakers. It's extra work for them and I understand it's frustrating.
It's not something that can be worked around. You can kinda get the same result, but it reduces the quality of the map. Being able to click a bonus to see which territories are in it, is an improvement to a map. INSS maps cannot do this anymore with this change.
Now you guys need to understand that having hidden bonuses that are identical to already existing bonuses has huge potential to introduce bugs in future features. It happened with Idle, that's why Fizzer changed it. But if Fizzer keeps reusing the maps for different gamemodes (like Clan Wars), it will be a problem eventually.
It happened once. INSS has been around for a long time. Also, the map for Clan Wars sets all bonuses to 0, so no worries there.
Edit: thanks Fizzer :)
