Some manufacturers make mcb shaped blocks of plastic for blanking out but I don't think BG do.. To leave a way in a BG spare for future is it acceptable to leave the slot empty and fit a blanking panel to the cover? It leaves a large section of busbar sticking out; not ideal but is it acceptable?
If you don't want to put an mcb/RCBO in a particular slot in a CU...

I have failed many a consumer unit due to the use of blanks that can be removed without a tool. 12.5mm is the limit and the MCB's are wider than that so you have to need a tool to remove blanks. So units you need to take cover off to fit them. They are OK.

I suspect it doesn't matter who makes them; they should still fit. Type testing hardly comes into it.
I think that's a horrendous practice. Circuit breakers should only be there if they actually have some purpose.
Not saying I'm a huge fan of it, but I don't think it's horrendous. It's not going to do any harm, and if they're labelled as 'Spare' then they won't even cause any confusion.
BG do make full size blanks. part CUA04, http://www.nexusinds.com/bg/uk/circuit-protection-accessories
And might be useful in case of a failure, or a need to add another circuit.
Yup. Especially 5-10 years down the line when someones fitted an LAP fuseboard and replacement breakers are rare as hens teeth!
More horrendous than being able to stick your fingers in and touch the bus bar? They do have a purpose, to fill the gaps in and make it IP2X.
From the BG website:
Quality copy editing BG, about as good as some of their stuff.

No, that is the purpose of a purpose-made blank.
Trouble is that the purpose-made blanks on many of the units now seem to fall out if you so much as look at them sideways. Better to have a spare MCB in place than one of those, or - if available for the particular board - perhaps an empty BS1361 fuse carrier.
Now the blanks on an old Wylex Standard are a different matter.....

Are you suggesting using an MCB to fill the gap doesn't make it IP2X?
