Does this still prevent  water or dirt ingress into places it should not go, or into the cable ?
Is the gland serving to earth the armour, and does it do so securely and in a way that will survive the full prospective fault.

Only if yes, and yes, I'd say its OK. Failure of either or these is probably an argument to re-make the gland plates with smaller holes ;-)

And even so why ? and what else is a bit funny

Single core so AWA cable? So could be aluminium glands, so would be bigger if same strength as brass.

Also some gland manufacturers specify the same size gland for different sized cables. Would need to check with cable and gland manufacturers 

Edit; just re-read this, apologies if you've thought of these already, grandma and eggs etc.

The terminations are inside a building and are shrouded.

Yes, AWA cable. The reason I say the glands are too big is that the back part of the CW gland is too big to provide a seal onto the cable.

(no apology necessary)

As long as they have gripped the cable properly then no issue. If they were BW glands you wouldn't even have mentioned it I expect. Only an issue if you need the waterproofing of the outer CW ring, which as you way its indoors , I can't see it being an issue
