Note that posing a risk doesn't just mean "if giant tree were to fall toward house it would be a problem." Obviously, you should monitor the health of any giant tree nearby, but by and large healthy trees growing tall is not an immediate concern. Moreover, some of those trees would be perfectly healthy if you kept them pruned to a safer height.

So, posing a risk is more on trees that are likely to fall over and do major damage. Or those that have root systems that are too close to your foundation and going to cause issue in that way.

All of this is said as someone that loves giant trees nearby. Seeing eagles and such nest at the top of trees that are hundreds of feet tall is very cool.

Edit: Also consider fire hazard to the house, depending on where you live.
