Weed proof fabric..

I'm not sure if I've put this in the right category but just after opinions... so we've moved into a rented property where we can do whatever to the garden within reason. So I've dug in a new border along the back of the house to be a pollinator beacon (hopefully!)  but whilst digging came up against a lot of weed proof fabric. So I pulled it all out. There were weeds on top of it and growing around it so it wasn't doing much of a job. A poor rose had a big horizontal root going over it into the soil a couple feet away. No worms. Surely this stuff is bad?  I might be looking to feel better now I've got rid but what do you all think?
