Target languages should not be automatically deleted when the language's tasks are removed

For classic projects.

It seems like a recent patch introduced a new behavior where empty language combinations are automatically deleted from the project when the last remaining language-dependent task is removed from that language combination.

Case:

If I create a class project with 10 target languages.

I then add task workflows for each target language.

Then at some point I had to delete the task workflows in order to change their workflows.

All 10 target language combinations are now automatically deleted when their tasks are deleted.

I would have to make sure to write down what my target languages were, and manually re-add them.

If the project was launched as a quote from the customer portal. I might have no records of what languages were requested from the quote.

XTRF support confirmed this is an intended behavior, but it didn't used to work like this.

Language combinations without tasks weren't automatically deleted in prior patches.

If XTRF intends to delete language combinations without tasks automatically, shouldn't it be made as an option that can be toggled on or off?

I also cannot find any documentation regarding this change. :(
