Just FYI for some perspective, many people (like me!) prefer field
mappings to property mappings for at least two (and probably more)
reasons:

1) we want to bypass (any) side-effects of setters/getters when
hydrating/persisting entities; yes, setters/getters with side-effects
are *generally* a code-smell but there are legitimate use-cases that I
don't want persistence-concerns to inadvertently trigger

2) property mappings lead to needlessly verbose public surface areas
on entities; not everything an entity needs from the database to do
its work is a good idea to expose to the outside consumer of that
entity (field-mappings more easily support the entity-as-domain-object
instead of the entity-as-DTO pattern that property-mappings encourage)

If we are voting (and FWIW I'm not sure we are!), I personally would
like support for field-level mappings ASAP; for me its a major
concession in the design of my domain model for persistence to only
support property mappings and FNH needs influencing the shape of my
domain objects feels like tail-wags-dog in many cases.

Just my $0.02
