This is the hub for EOL standards and protocols
EOL in these categories may mean the standard or protocol is only grandfathered into new code and devices, rather than a specific end of support, since there may never have been specific support for the standard or protocol from a vendor. This might better be termed Obsolete rather than EOL.
