I've had bamboo in the garden for over 20 years and had no major problems. One clump forming variety who's name escapes and one area of Phyllostachys aurea and Phyllostachys nigra. Neither group has been invasive. I've had a couple of runners try to escape from the Phyllostachys but it has been the work of a few minutes to cut off the runner and pull it out. The line the runner has taken is pretty obvious so all it needs is to cut a channel with a spade along the line and haul it back out. There are many plants which can become a problem if they're allowed to but that doesn't mean they can't or shouldn't be grown.
I accept that would be more problematic if it was under paving but they are categorically not thugs in my long experience of them.
