Waterlogged lightning rod

When testing the new snapshot of 1.17 I have been able to make cool looking structures using lightning rods (eg:-bridges,pipes,ropes) but when placed in water they cannot be waterlogged. I know it wouldn't make any sense for lightning to get attracted underwater so just make it so that lightning rods become useless underwater/become useless when waxed so that it could be used in builds involving (eg:-underwater pipes, wreckages,...) and not burn them down
