I agree with @mistfpga point. I was also under the impression that in the case of a shortfall that ECC would be able to apply for a Grant to make up the difference.
If this is not to be the case, then my concern would be that the ECCs stance of “All in ZEC” will become “All in ZEC* … *depending on ZEC prices”.
I understand the spirit and the desire to get other parties involved with Zcash development via MG but adding the exclusion of the (currently) most qualified group of people who know Zcash to not be even able to apply seems to potentially be counter productive.
