----------------------------------------

Raising it to a higher value is fine by me.

> We've had some users recently complain that the default MAX_SUBST hardcode of 20 isn't
sufficient for their substitution needs and they wished it were configurable rather than having
to roll about with workarounds such as using temporary smaller substitutes and then building
the fuller one after it. We should consider raising the default hardcode, or provide a way
to make it configurable instead.
