will aternos accept modpacks with CatServer?

Okay so there's a nice server client called CatServer that let you use mods + spigot + bukket for version 1.12.2

I'm now making for my modpack a server package and i wanted to ask if aternos will support plugins if the server package is using sponge/CatServer?

Modpack: IsekaiCraft

Launcher: TechnicLauncher
