Honestly....... no.

ive installed 2 i think with cavitys. and it was build regs for upgrade on the refurb so down to builder really..

few posts on linkedin about it latly
 
I think it would only matter if there's signs of damp, so they want to make sure if there's nothing sits on the cavity tray to bridge maybe.

I've seen it on LinkedIn aswell
I would just say if the walls are dry internally you should be ok
I wouldn't be knocking holes in the walls to check
