Does the 'stairs that can be ascended but not descended' trick work in modern source ports?

I kind of want to add an area where you go up a flight of stairs, and when you try to go back down, it bumps into the ceiling, triggering a lift that sends you up into another area. The original area would be made available through a one way drop.

 

Would this be possible in, say, GZDoom?

Yeah, of course it's still possible.

 

Though some players may decide to crouch so as to go down the stairs once they know they can't go back down normally.

Did a quick test, can't get it to work.

 

I found a workaround though: at the beginning of the stairs it lowers the lift that is raised by 8 units, allowing you to walk under. By the time you hit the end, it will have just come back, meaning you bump on the ceiling and trigger the lift up.
