Any comments from airways sector ATCOs?
It's a pity you feel these differences and logically get confused at them.
Simply don't forget that old habits are almost impossible to change, whether or not regulations have changed a couple of times...

In France, "proceed to" is now forbidden, but loads of elder ATCOs and their trainees, then operational ATCOs ! will still say that.
For me it's plain simple:
* "direct (waypoint)" if only a waypoint to use
* "route (waypoint1), (waypoint2), (waypoint3)" if several
*"keep heading XXX°" for spacing
* "resume direct (waypoint)" when spacing action is over
