You can print yourself a chart or calculate positions using whatever epoch you want ... if no other publication publishes coordinates in the epoch you need for your chart - its a bit pointless.
Historically charts were made using B1900, B1950 and J2000. So odds are no one will care much about anything but J2050. I think adopting the next "standard" epoch is also usually slow. IIRC (and its a while since...) in the 80ies and even 90ies much still refered to B1950. I suspect folks might abolish changing epoch entirely, as for any precision telecope pointing you'll have to transform to current equinox, anyways. So there is really less and less benefit of using coordinates that are close to but not exactly current equinox.
The astrometry folks also have given up on adjusting anything to our solar system, actually even to our galaxy. All that unstable junk moves too much by todays precision standards ... They go by extra galactic radio sources and their ICRS system, essentially J2000, is fixed forever. Wait, 'currently foreseeable future".
