I don't follow you here.
These were the three first names of interrupt controllers introduced back
in 2.1 and the names chosen looked consistent.
I'd say they *only* looked consistent then. :-)
In fact, i8259.c is driving two coupled together 8259 chips, so using the
word "XT" in this context was absolutely wrong.
As for the I/O APIC, I think i82903AA was "the reference design" for it...
