provided alternative homing support:
For 29 of 33, non-homing F and J were in the base or alphas kit.
Four of those 29 also had homing U, H, T, and N in the base or alphas kit.
Some sets added other home keys for various reasons:
E to support BÉPO and Neo layouts (11/33)
E + I and S for middle finger homing on all layouts mentioned above except Neo (5/33)
A to support the QGMLWY layout (8/33)
D and K for QWERTY middle finger homing (3/33)
Perhaps to minimize kit count, SLK Dessau's homing U, H, T, and N were part of its International kit.
