Sorry, this was a typo.
/* Degree of chromatic adaptation */
s->D = 1; /* s->F * (1.0 - exp((-s->La - 42.0)/92.0)/3.6); */
Is that how you did it?
Yes.
Any cons to this change? Never that nice to hardcode something

Definitively it should not be hard-coded, since the calculated D
is certainly appropriate for many use cases.
But I don't see a reason why an option to override D should not
be exposed on the command line, since other CIECAM02 parameters are
already offered as command line options as well.
[ for instance as -cD:... and -dD:...]
