That patch has been merged. However, the part about merging
:myProperty+: into :myProperty: did not work as well as I thought
initially. Now, all the instances of :myProperty+: do get merged and can
be accessed via (org-element-property :MYPROPERTY+ element). However,
they are not merged into :myProperty: because it would interfere with
property inheritance.

Merging everything into :MYPROPERTY is possible, but it might break
third-party packages that do not expect element properties to be lists
(currently, most export backends assume element properties to be strings).
I am reluctant to work on this unless Nicolas displays a clear support of
such change.

An alternative could be modifying org-element-property or
org-export-get-node-property to support multiline properties.

Meanwhile, export backends might be changed to look into :PROPERTY+ in
addition to :PROPERTY. For org-export-taskjuggler, you may implement
this feature yourself. Note that org-export-taskjuggler is not a part of
Org core. It is in org-contrib and currently not maintained.

Best,
