> even if we could load the elevate.xml file from the data
folder in Cloud (or changing it directly in zk), does this make sense in
terms of performance? We have frequent commits and a big elevate.xml file.

In terms of performance a big elevate.xml should not be an issue. The
structure used for query matching is a tree-like and supports a large
number of elevation rules even for subset matching (though it uses more
memory). Do you use exact or subset matching?
I'm going to fix this elevate-in-data-dir issue in branch 8.9.
