In practical terms, CCS and J1772 are the same standard, in the sense that 2 prong and 3 prong US power plugs are the same standard, since receiving plugs support both.
I do still see CHAdeMO at a lot of EA and EVgo stations (I usually charge at home, so my charging station experience is mostly limited to road trips)
Around here EA's upgrading to CCS-only stations. The older non-upgraded stations only have a single CHAdeMO plug that is usually out of order because it's on very old hardware.
