After EZP-19865 was fixed, it is possible for front-end siteaccesses to share session ( like they do in 3.x and 4.x )

However, this feature is not enabled by default by setup wizard when installing ezwebin_clean_site

I assume the same thing goes for ezwebin_site,ezflow_site, ezflow_clean_site, ezdemo_site and ezdemo_clean_site too
