personally i would like A LOT (eg to buy and use) routers, switches that able to pull up to 2.5gb or 5Gb bandwidth/load over legacy Cat5e cable(eg with NBASE-T Phy within them).
What are you asking?
its was typo/mistake in title, sorry. trying to correct that. 2.5GBASE-T and 5GBASE-T meant
some links to relevant RFC or wiki, like say https://en.wikipedia.org/wiki/2.5GBASE-T_and_5GBASE-T

there also was “open” competive standard called MGBASE-T

generally ability to 2.5x-5x increase performance over existing network/cabling sounds cool anyway, cuz upgrading gear in most cases - much less painful that re-wire network/cables itself.
so far only marvel - already shipping their 2010/2040 Alaska trx/phy, but broadcom and Aquantia - will mean too(not sure about Qualcomm, but i would be surprised if they leave that piece of pie too .
suddenly it all make bit more sense in 1900-3200 AP’s usage in SOHO, for example. let alone corporate environment
