Really, it will remain that way until the bandwidth needs from the

At which point the 8P8C connectors on desktops and laptops changes from RJ45 to
SFP+ cage  with  LC connector,   or  direct-attach SFP+   between
laptop and    "active"  fabric extender in the nearby wall jack;  fed
by fiber, with 10G-SR optical...

Because the  copper spec for >1gig  was  10GBase-CX4;  much heavier than Cat5.
And there won't be much tolerance for the copper 15 meter distance
limit in any case.
