I consider that level is linked to the local numbering of the building 
(if present). so if a building has a level 12 and then 14, I will never 
fill in level=13, no matter if it is in a country where the ground is 
represented by 0 or 1
in the same way, if a building has a level 0 0.5 1, I don't see any 
reason to invent another numbering which often becomes incomprehensible 
(osm would be unwise to give a company a level=x when it is something 
else indicated on the spot)

the best thing would be to talk to them about it (and until then, we can 
consider the tag as poorly documented and therefore not usable in this 
country)

I very rarely put level=0 and almost systematically level=1,
do you deduce that I'm in a country where level=1 is dominant ?
no, I simply didn't put level=0 on 99% of the items I create
if the building have no level<>0 items, I nearly never add level=0
to shop at the ground level for ex.
I'm not saying it's a good thing, it's just my experience.
