Probably Microchip feel that they warned programmers of that era,
like me, who then stopped using TRISx. Newer programmers would
not likely be aware of TRISx and so the warning has not continued
into more recent revisions of the datasheets. However, it still works
(because of my suspected disruption to legacy code) as long as you
use a chip of that era

A very very new PIC like the 16F1827 does not support TRISx

  tris  portb

Warning[224] : Use of this instruction is not recommended.
Error[126] : Argument out of range (0D not between 05 and 07)
Build Failed

Manually inserting 0x0065 gives TRIS FSR0H, which is a nonsense
instruction
