High speed, low-latency, interconnection in clusters is not done via rcp or scp. Also, encryption has lower performance impact than some would assume.
Nonetheless, even if there is a cluster environment using these old commands for some perceived performance improvement, they're certainly running a bunch of custom software; it's not gonna be a stock OS install. So, there's not gonna be any harm in having to install an extra package to get the r commands.
Having it there by default to serve some tiny segment isn't really sensible.
I'm not saying eradicate these commands from the face of the earth. I just saying putting them into the default installation of any OS in 2017 is an unnecessary risk.
