I won't get in to the best way to accomplish this technically, but I
suggest you remove the existing boundary information in whatever way
works for you while leaving non-boundary information intact, and then
upload your new information keeping it separate from any other
(non-boundary) objects.
As other people have discussed, it can be very hard (requiring legal
research or even court decisions) to know whether a boundary IS a
certain feature and will change if the feature changes or merely
currently follows a feature and will stay put if the feature changes.
Uploading the boundaries as separate objects is not wrong and provides
the vast majority of the value. If anyone is motivated to do the legal
research and connect things when appropriate, they can do that later.
