What makes you think they can't be?

Hate to say it but

CEF DL boxes are quite good

sorry

My favourite DL boxes are Appleby, they never give problems, but some of them are dire.

If you really think you are going to have a problem with your dimmer, TLC sell metal dry lining boxes complete with an intumescent seal in the back.

Its allowed, but go for as deep a box as your can to give extra air space around it.
