We could also consider making 1.8 server advertise skelta mode capability
by default, with an option to turn it off, so that 1.8 clients will negotiate
skelta mode with 1.8 servers by default, but not with earlier servers.
This way, 1.8 clients talking to 1.8 servers can take advantage of skelta
mode, while clients talking to older servers won't stress out existing
installations by default.
In the 1.8 release notes We can raise attention in the fact that a 1.8
server should turn off skelta mode if necessary, such as when each GET
request causes an authentication request to LDAP.
