Non standard stuff and lack of implementation of entire standards  is 
still present today:

it seems a required part of how programming languages change.  Co-arrays 
seem very helpful, making a nice PGAS language out of old Fortran, such 
transformations seem to be more difficult for other programming 
languages (C, C++,Ruby,Rust,Java etc). Many PGAS languages lack fault 
tolerance, which most big data frameworks have. On clusters of 
workstations in production environments, fault tolerance is useful, and 
code portability may prevent big data workflows being transitioned to 
PGAS type languages.
