Hi James,
it is not necessary and was fixed along with other changes as part of
GEOS-7884:
https://osgeo-org.atlassian.net/browse/GEOS-7884
Some of the changes made it into 2.10.1 release (including the GWC one you
mention), others landed
later.
I'd advise to check out a nightly build and see if you are experiencing
residual problems (the fixes landed on
all series as far as I remember, if you want to be extra sure check the
master branch):

Wondering, are you using jdbcconfig or sticking to the default catalog?
Cheers
Andrea
