I am of the opinion that your main problem is not a technical limit but one of (practical) maintainability and feasibility. As the numbers of ACLs increase it will get increasingly troublesome to keep track of all the different rights, regardless of any technical limit being hit or not. I suggest to look for a different solution - ideally one which uses only standard UNIX privileges.
For instance, look for ways to sort your users into groups, then give respective group rights to corresponding directories.
I hope this helps.

g_destroy_consumer
G_CONSUMER(9) BSD Kernel Developer's Manual G_CONSUMER(9)
NAME
g_new_consumer, g_destroy_consumer -- GEOM consumers management
SYNOPSIS
#include <geom/geom.h>
struct g_consumer *
g_new_consumer(struct g_geom *gp);
void
g_destroy_consumer(struct g_consumer *cp);
DESCRIPTION
A GEOM consumer is the backdoor through which a geom connects to another GEOM provider and through which I/O requests are sent.
The g_new_consumer() function creates a new consumer on geom gp. Before using the new consumer, it has to be attached to a provider with
g_attach(9) and opened with g_access(9).
The g_destroy_consumer() function destroys the given consumer and cancels all related pending events. This function is the last stage of
killing an unwanted consumer.
RESTRICTIONS
/CONDITIONS
g_new_consumer():
The geom gp has to have an orphan method defined.
The topology lock has to be held.
g_destroy_consumer():
The consumer must not be attached to a provider.
The access count has to be 0.
The topology lock has to be held.
RETURN VALUES
The g_new_consumer() function returns a pointer to the newly created consumer.
EXAMPLES
Create consumer, attach it to given provider, gain read access and clean up.
void
some_function(struct g_geom *mygeom, struct g_provider *pp)
{
struct g_consumer *cp;
g_topology_assert();
/* Create new consumer on 'mygeom' geom. */
cp = g_new_consumer(mygeom);
/* Attach newly created consumer to given provider. */
if (g_attach(cp, pp) != 0) {
g_destroy_consumer(cp);
return;
}
/* Open provider for reading through our consumer. */
if (g_access(cp, 1, 0, 0) != 0) {
g_detach(cp);
g_destroy_consumer(cp);
return;
}
g_topology_unlock();
/*
* Read data from provider.
*/
g_topology_lock();
/* Disconnect from provider (release access count). */
g_access(cp, -1, 0, 0);
/* Detach from provider. */
g_detach(cp);
/* Destroy consumer. */
g_destroy_consumer(cp);
}
