Residents can place redstone torches next to tnt

was testing on my alts realm to see if there was anything that residents can do (im having somebody do a job for me and i gave them resident role, want to make sure theres no way they can steal my stuff)

i found out that while u cant light a tnt on fire with a flint and steel or a flame bow while resident, u can still place a redstone torch or lever next to it, and use those to ignite it

ik this seems like it should stay but it doesnt really make sense that residents would be able to use redstone power to light tnt but not a flint and steel
