I think HBD is very important to Hive's future, as I would hope should be indicated by the changes we've coded to improve it.

I haven't seen the comments you're talking about, so I can't comment on specifics of what you read. But it is true that I don't agree with every proposal made on how to go about improving it.

For example, I don't agree with subsidizing a HBD liquidity pool with the DHF, especially in off-Hive markets, as that just seems to be a case of subsidizing someone's external market (via the fees collected) and the traders who operate there (via the decreased spread).

Any good liquidity pool should be self-sufficient, IMO, based off the spread that it market makes over. This is certainly the case of the HBD stabilizer, for example, as it makes a profitable return for the DHF.
