Perhaps RGBLIGHT_ENABLE = yes should be in keyboards/4pplet/aekiso60/rev_a/rules.mk and keyboards/4pplet/steezy60/rev_a/rules.mk, if both keyboards support RGB underglow as a regular feature...

I would prefer it like this, you can easily enable underglow in the rules if building QMK. There is no keycodes to turn off underglow etc in the default keymap so I'd argue it makes sense. For VIA on the other hand, the feature need to be enabled. :)
