does anything read switches::kDisableHostedAppsInWindows? (or will it in a
follow-up?)

Perhaps just use SINGLE_VALUE_TYPE(switches::kEnableHostedAppsInWindows)}

The follow up will be to flip this flag from checking enable to checking
disable, then removing the switch entirely once it's stable.

Hm, typically both switches are checked regardless of the default (see, e.g.,
app_list_swiches.cc). I guess it works out to be equivalent though.
