I didn't catch the jump here. There's no assumption that code and data and names are mixed ... its a common implementation approach, but its perfectly possible to have:

Data -> up .... down <- Heap | Code -> up ... down <- Names

Hence words like COMPILE, and , which in mixed classic threaded systems may be:
   : HERE ( -- a ) DP @ ;
   : , ( x -- ) HERE ! DP ++ ;
   : COMPILE, ( xt -- ) , ;

... and on split classic implementations may be:
   : HERE ( -- a ) DP @ ;
   : , ( x -- ) HERE ! DP ++ ;
   : CODE-HERE ( -- a ) CP @ ;
   : COMPILE, ( xt -- ) CODE-HERE ! CP ++ ;

... so while COMPILE, is often about things like compiling the call along with the routine address in a subroutine threaded Forth, it's also part of the separation of codespace and dataspace.

And of course, in many umbilical Forths, the namespace stays on the host machine, and only specific names required for operational purposes are ever compiled onto the target system.

In general ANS Forth provides the words that allow us to refrain from assuming that we are mixing code and data in the same area.

That also seems a fairly conventional thing ~ specific implementation specific features accessed via implementation specific flags or prefix or postfix operators. Though it seems like the multi-processor Forth systems have been more successful in maintaining ongoing support on decade plus time scales, and it may be that the single processor implementations are more inclined to focus on providing that kind of tailoring.
