There isn't a "potential performance regression" that is in any respect
different from the already-committed changes for non-Datum sorts.

Also as I've pointed out, it's not even clear that there is a regression
at all, since I've already shown that changes of several percent in
timings of sort operations can be caused by irrelevant noise factors.
To actually show a performance regression of less than 10% or so would
require, at a minimum, showing two different timings using the same data
and the same binary, though even that is subject to noise; to really
prove it you'd have to show a statistically significant difference
between sets of binaries with random padding sizes (see the graph I
posted on this point).
