Delete Branch "%!s(<nil>)"
Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?
The "Attribute" node in shader node trees could support attribute search based on the context data. The search code would be generally the same, but the data would be accessed directly from the evaluated geometry set of the active object.
Therefore attribute search should not be used when the node tree is pinned, or alternatively it could depend on the pinned object context of the node editor, if that is available.
Note that fewer attributes are available for EEVEE. There will have to be a special case there until more attribute access is implemented there.
Some starting points / references:

Hi, I'd like to have stab at this, I wonder if you could expand on "the data would be accessed directly from the evaluated geometry set of the active object." Is this the alternative to the way the search in geometry nodes accesses/stores the attribute data in the node ui storage? So instead of having to store the data and later access it, it can be directly accessed through an existing api?
Yes, exactly!. Using
object.runtime.geometry_set_evalIs this in the python API? If so I am having trouble finding it. I have found the corresponding c function, but I am yet to find any usages of it in the source to see use case examples
