Thanks for the info! -- I assume that the OS versions listed in the URL
above correspond to the first version of the OS which included support
for each feature... Skiming through the list, it seems that RDNSS
support was added to "latest version of X", which in most cases dates
back to only a few months ago.... Thus, I don't think one could rely on
support for such RDNSS, unfortunately.
-- not to mention that no version of Windows supports it... which in
most general scenarios makes this a "show stopper".

Even "implementation-wise" (i.e., even if SEND were deployable), it
would take years before OS versions with support for SEND replace
existing installations. -- That essentially mean that it would take many
years before you could actually think/try about deploying SEND.
