i'm sure they care !
otherwise any year they could select 200k people , and there would never be a year with 35-46K visa issuance ,
yes they warn , that selection doesn't guarantee .... but they try to have less disappointed people , this is for sure .
And regarding to additional selection , why they should use postage ? what cost?
in 1st may they inform everybody to keep their confirm. number - and many people for example kept waiting for october draw this year.
so why they cannot IN CASE OF ANOMALOUS YEAR(and judicial problems) , make several draws , maximum 2 times , to have enough sent forms and fill the quota?
what is easyer ?
in case IF ANOMALOUS YEAR (and judicial problems)happen ,to make 2nd draw in october , then if need make one more in january (still enough time to send docs)
or - every year choose 40% more then need selecties , thinking that one day ,in case IF ANOMALOUS YEAR (and judicial problems)happen , it could help them to fill global quota
