IMHO some things shouldn't be exposed as properties - they should have
their own command-space. This is especially true of something like
the EOL handling since it drives functionality that mutates committed
and checked out content. Of course custom properties are used in
Subversion as well and supporting that is a good thing for those that

Even if this were implemented as properties, I would expect all
properties under a special namespace (EG 'bzr:') would be hidden from
prop-get, prop-set commands - each would, I expect, have it's own set
of CRUD commands.
I agree that exposing this as a property in Subversion was a mistake -
it should be clear to users that setting it changes tool behaviour -
Properties in subversion look more like data than configuration and
that can be confusing.
None of this should detract from the huge benefit this addition makes
for many users allowing more projects to move to Bazaar.
