No, there isn't. You are talking about a few ounces, tops.
No, none whatsoever. You could leave the bulb, transformer and BRCB dangling the whole weekend and it would not affect any part of the installation one whit.
When strain relief *serves a purpose*, that's an appropriate use. When there is NO strain, as in this type of installation, there is no strain relief fitted because the trade and the regs people recognise there is not a problem.
'Bout time you did, too!

Strictly speaking, to meet the regs there should be strain relief on your junction box.
Nonsense. How would you then gain access to the junction box to replace the transformer through the small hole in the ceiling? Lift the floorboards in the room above?

You pull it down in just the same way that was shown in the photos. The difference is that the strain, such as it is, is carried by the sheath of the mains cable rather than by the individual wires where they are fixed by the grub screws inside the terminal block.
Identically, IOW, to how a properly wired mains plug is done if you DIY it.
How many more times! There is NO strain when the whole caboodle is in situ. Any slight strain that could occur only when the bulb-cum-transformer is dangling through the hole during replacement is going to persist for about three minutes only, or as long as it takes to loosen the screws, replace the transformer, tighten the screws and push the bulb holder back into the ceiling.
Besides, this glib "carried by the sheath of the mains cable", where are you suggesting the sheath be attached to provide the strain relief?
Here is a typical junction box:
See any strain relief for the mains cable sheath anywhere?

I never said there was.
Ah, you understand at last. Well done - that was the strain I was talking about. And if the cabling gets disturbed from above, as it might be because plumbing is being done or for other reason, I'd personally feel happier if I knew that the underfloor cabling was
*robust* against such disturbances and did not just rely on the grub screw in the junction box.Indeed not, so I'd call this a rubbish product. Try this instead:
You'll note the cable clamps where they enter the box - just like a mains plug you wire yourself, as I said before, but perhaps you missed that bit.
I know what a typical junction box looks like, And its the wrong junction box for the job.

How about dangling a baby's thumb off the bulb holder, because that's about the level of strain you'd find.
Well, then, you make yourself feel happier by all means. But I am NOT going to rewire my house, okay?
It is a perfectly suitable product for the job it has to do.
No.

Its not a rubbish product (at least not for that reason), it just expects you to clip the cables to the surface properly at the entry points.
