Well, you still have it. GNU APL is there, and you really don't need a dedicated keyboard. It didn't take me long to learn the layout, and the Emacs mode provides a shortcut that pops up a picture of it to help you learn.
Also, all modern APL implementations use Unicode, which contains all the APL characters so there is no need to mess with special fonts something like that.
