Aye no worries. On the topic of cheesing mechanics, it will always happen, there is no possible way for even the highest budget and perfect and most intelligent and well trained devs of any game to figure out what every single player is going to come up with when given an ability/item/whatever the game has. Many devs even enjoy when something is cheesed and/or broken (*Note on this below). The fact that 0 damage = no debuff even exists proves Squeenix is largely okay with cheesing happens as long as Bolide and Hallowed both nulify all damage. It would be pretty easy to either remove that fact or make it so they cause you to take only 1 damage instead.
*I recall watching the devs behind Doom Eternal watching a speedrun where the speed runner exploited a bug that would essentially launch the player beyond the levels bounds because of a feedback loop in the physics engine. Instead of saying they should patch this out and make sure it can't happen, they instead said they should put little hidden messages behind level borders for speedrunners to discover. Things like this are probably why Squeenix supports it. A player finding something creative to do with an ability you created feels nice sometimes.

EDIT: I feel like the forum is calling out my fantasia addiction. This stuffs like Skooma.
