Currently, FLAG(PAGE0) flags all explicit references in which the base

fairly common practice. (Many years ago instructions coded this way
actually ran slower, but that hasn't been true for a long, long time.)
Furthermore, many instructions in AR-mode programs *must* be
deliberately coded in this manner. Whether optional or required, such
instructions should *not* be flagged as PSA references!
I think you may have meant that it flags all -implicit- references in
which the base register is zero. As I understand it, one fix for the
assembler complaining about 'B 4(R14)' is to explicitly code it as
'B 4(R14,0)'
