It seems there is a consensus that the discount should be reinstated.

We will enable the discount now. For contracts which volume is at least 100 hours will be an additional 10 ores deposited for each 10 hour unit, that means a 100 hours volume contract will be entitled to 1,000 ores and GDC. Since there are 10 hours VICR contract exists, users who buy at least 10 VICR contracts will be receiving the extra 100 ores deposit. Numerically, that was the previous discount as well.
