Yes and the GUI uses the "mandatory" hint and does not let you apply if
you delete the mandatory argument. That's not the point here.

You are most likely right and I will fix it in DRBD-MC. On the other hand,
I am fan of as small config as possible (it is more readable and less
error prone) and then if something has a default value I would expect that
RA uses it as a default. Other question is what should happen if default
value changes in the RA during upgrade, it depends on the application I
guess, but usually you would want to keep the previous default.
