Change is good, imo...

...but trivial to build a client that filters on FID.

Stated vs. revealed preference might be different, though :)

All that's needed is a way of tracking positive reputation. Low FID is a very rough proxy to start. I think clients that support filtering on reputation will go far. 

I'll link a relevant insight from a paper on reputation in markets 1/3

Scenario: Participants can lie about quality of goods, but reputation is of each identity is tracked

They tested 4 configurations. tl;dr is positive rep is enough

Building global interoperable roles @ hatsprotocol.xyz | DAOs are the endgame of crypto

4 configurations + end states:

1) Can't change identity -> high quality transactions

2) Completely anonymous system -> low quality

3) Can change identities, only negative reputation tracked -> starts high, ends low

4) Can change identities, only positive reputation tracked -> starts low, *ends high quality*
