No, that won't be able to read the input any more, but I think it is ok: 
as you say this isn't such a useful thing to support, and it doesn't work 
in the Windows version either.

My main reason for doing this change was as a first step towards 
supporting a way of attaching Allegro drawing onto an existing window: if 
we are going to add functions for that at some point, it is important to 
be able to initialise the system without creating a window automatically, 
so you later have the option of either calling set_gfx_mode() or 
attaching it to an existing window(s) of your own.
