so this sentence is not quite true.

But one can't change it without breaking the totally frozen fm/mp
dotlabel. Following would look more orthogonal, but it's impossible to

vardef thedotlabel@#(expr s,z) =
    interim linecap:=rounded;
    draw z withpen pencircle scaled dotlabeldiam;

def dotlabel = draw thedotlabel enddef;

dotlabel(btex $A$ etex, origin) withcolor red;
label(btex $A$ etex, (10mm,10mm)) withcolor blue;
draw thedotlabel(btex $A$ etex, (20mm,20mm)) withcolor red;
draw thelabel(btex $A$ etex, (30mm,30mm)) withcolor blue;
