Hello,
if Google Translate does not fool me, then the Japanese EA version provides lots of very useful free Add Ins that are not available to the Rest of the World (ROW). e.g FTA Analysis, Extended Traceability Matrix, ...
Some Add Ins have an English Language Version already and could be very useful for the ROW.
I would even be ready to pay for some of those instead of rolling my own.
Currently they are inaccessible even having an active Maintenance Subscription.
Please think about it. If you really want to push MBSE, then that would be a smart move
