Nit: This comment is vague ("experimental features"?).

Can we get by without a flag at all?  Seems like you could just check this in
enabled, and go back and revisit if there are problems.

We agreed to put the features first behind the flag so it's easy to disable the
features with a small change (e.g., reverting the CL which turns the feature on
by default). This sessionStorage feature is the experimentalest of them all.

I changed the comment though to mention sessionStorage since it's the only (and
the last) experimental feature this flag will affect.
