Wiska boxes with wagos

I will ignore for now the question of mixing manufacturers, and how this affects type approval, as I think it is similar to the arrant nonsense that suggests a 16A MCB on a DIN rail knows who made the rail and box, and changes its behaviour, but does not apparently care about the number of other MCBs sweating away  beside it or the size of wire used or how well it is done up.

The question is ‘is it bad practice to let connector blocks (of any kind)  flap about on the wire ends in a box.?’

Maybe, if this is a place with a lot of vibration or sudden acceleration, where the flapping about matters because a wire may get fatigue failure or shake out. If however it is not a fun-fair ride or something, then the other big question is do the cables get pulled?. We'd hope that any flexes would come via a compression gland that held it tight, and any rigid wiring was held by clips or cleats. 

Apart from the spaghetti problem of  lots of tail end not fitting in the box, and perhaps poor airflow if the box is too full, I see no real issues, after all a similar approach seems to work for telecoms. 

It is however a bit ugly.
