Separately, regarding this discussion, I see a mention of "filtered hoisting"... filtering and hoisting are two different things... although both show a subset of the tree, they serve two very different purposes. Filtering shows the whole tree with some branches hidden. Hoisting takes one branch (and all its sub-branches) and makes it the root of the tree. I guess you could have a hoisted branch that also has its sub-branches filtered, but they are two distinct things.
I think hoisting can be conceptualized as a special case of filtering, and the filtering you propose would yield hoisting as a particular case. Your filtering allows the display of branches and their descendents. The filter excludes everything but certain branches, whose descendents are also displayed. If you filter so that either only a unique branch is selected or no branch is selected outside a unique branch and its descendents, you have a hoist.
