a soft delete of pricing is a must have now, we have the same probleme in so many packages . we are sure the term price is not used anywhere . when we have imported from v2.5 , some package has a lot of term price doubled 10 times or more, and we can't delete it from admin UI , an we can't restrict package as it used in so many plans .
no time for me to enter database & delete about 100 lines .all of them are 1 term with price 0 . i remember a task for this already exist . i hope it done in v 4 .
