Would It do to plant on, or around then inwards for the vicinity of the invasion? A fresh layer of soil with mixed in germinated oregano seeds should do good if they are as effective as that I would think.

A vigorous variety of winter squash, running cowpeas, grapes, velvet beans or some other annual legume might be worth trying. Replant the annuals every year around the edges, densely, and try to provide them with a competitive advantage in moisture and fertility. The ultimate player, of course, would be kudzu, but that might be replacing one problem with a worse one!

At the start I was just thinking about reducing the weight of blackberry vines crushing down on the more decorative bushes. Now most vines are gone, or come in all soft and tender. It used to be hard work, this year it seems very minimal, it might be possible to eliminate it if I spent another few years doing it. With selective pruning of only black berry vines all the other bushes seem to have done better. It even turns out there was ivy and wisteria under the black berries!
One thing I regret is that I planted two mint between my raised beds and the bramble groves. Now there are a few black berry tendrils coming up in the beds and a lot of mint. At least it works in smoothies and mojitos and doesn't leave alergic scratches all over my hands.
