It's normally a moot point on a data volume - before it's even
approaching 95% usage you'll generally have already planned, if not
implemented, the larger replacement.

Really, the space is most useful on volumes where it's important (or at
least desirable) that even if a normal user manages to create a runaway
process that eats all the space, a privileged user will be able to
perform operations that involve writing to the volume.

Outside of those, as with your data volume, there's no real need for
that reserved space, but it's not common to gain much out of removing
it either.
