sorta. Theres two issues in that. Are properties immutable (ie unable to be
changed) ? and will "configuration" of tasks pick this up? The first issue
(ie making properties mutable rather than immutable) had no clear consensus
IIRC. The second issue is mostly true of current ant *except* in certain rare
occurences (when the same task is executing multiple times - like from a
script but property values have changed). We will just fix this minor and
rare case and thus allow easier manipulation of ant systems from your
favourite scripting language (javascript/python/whatever).

Yep. Not sure 100% on what Ant2 will do here though.
