Evolution of tech will eventually push 1G into mGig (naturally), same way 10/100 was pushed out a while ago. My assumption is in 10 years, I don't think you'll be able to buy a 1G switch anymore lol. As for now: Wi-Fi 6 , nah Wi-Fi 6E (still at least 3+ years away for 'large' client adoption as well) - then yeah mGig might actually be nice to have. Need is a strong word because of WAN limitations, but if your traffic is LAN based, and your rocking 160MHz on 6E, or using all 3 bands on the radio, then yeah mGig will actually come into play. https://www.youtube.com/watch?v=8gvB5MCi9do With 6E, 80 is going to be the new 20, with regard to MHz. If your in a country that will get all new 1200MHz, then there will be more 80MHz channels in 6GHz, than 40MHz in 5 GHz, currently. Bonus - none of them are going to be DFS, so yeah. The only scenario I can see of going below 80MHz in 6GHz space would be for stadium/LPV deployments.
