CHAdeMO is still very readily available at almost all DCFC stations, even the new ones. Many of the EVgo DCFC stations here have CHAdeMO--->Tesla adapters chained to them, and I've often used CHAdeMO with my Tesla (especially in Canada) using my own adapter. Yes, I think it'll be around for many years to come and I hope to someday rig a 'clean' CHAdeMO setup to utilize my i-MiEV as V2H. The problem is simply getting access to those CHAdeMO stations, as almost all stations are shared with SAE/CCS and so many EV newbies need to be educated in charging etiquette.
