hive.fund is included in current supply and all of the supply figures. However the HIVE that HBD can be converted into is not included in current supply (it is included in virtual supply). This applies whether or not the HBD is inside hive.fund. By sending HIVE to hive.fund, it is converted into HBD and thus removed from current supply.

Hard to say if the proposals that have recently lost funding would be better for Hive

Seems like a matter of degree to me. When HBD was only a little above, the return wasn't so huge, and the other proposals can be left alone. But when DHF can double its money instantly, it seems reasonable to me to take this opportunity to grow the fund as well as reducing HIVE in circulation, and resume the proposals later.

As noted in the post, the proposals all got extra funding for about a month due to HBD being worth more than the assumed $1 (though not to the current degree, generally only 10-30% extra), so that's another reason some interruption doesn't seem like a big deal to me.
