Pretty simple really, 10Gbps copper needed new cabling which turned out to be a big hurdle in the real world.

2.5GBASE-T and 5GBASE-T do run over existing Cat5e cabling reliably.

10Gbps copper Ethernet runs just fine over cat 5e/6 cable, but not at the same distances possible with 1000Base-T.

It'll generally work for a few metres with Cat5e, but I think it's always been too problematic to be officially supported. Though looking around it seems some manufacturers do say it'll work?

It works fine over Cat6 yeah, but if you've not got that deployed then 2.5Gb or 5Gb is a good step up from 1Gb.
