Those developers (I'm part of them) have every interest in keeping code
working and up to date, because their incentive in doing this bridge is
to eventually to use Zope 3 proper.

No. Here at Nuxeo we are writing products with Five with the express
goal of being able to port them rapidly to pure Zope 3 when we have
enough Zope 3 components to build a proper CMS. Views and adapters,
together with a few core utilities, make up 95% of what most products
need from their framework.
