Be aware that animals (both domestic and wild) in the garden can trip on the drip line and pull it apart.
Also, if you live in an area where there are a lot of rats (we live in Rat Haven thanks to all of the oak trees, which harbor rat nests), be aware that rats love to chew on drip lines (and also netafim). Because of this, except where absolutely needed or there was no better solution, we have torn out most of the drip and netafim from the garden. The rats kept chewing holes, which can be hard to find (especially under heavy groundcovers), so we ended up with a lot of leaks, higher water bills (due to said leaks) and some dead plants (because they weren't getting water, because of the leaks).
Not a fan of drip or netafim here, though I admit that they have their uses.
Good luck to you!
