I had to figure this one out myself a few months ago. See src/common/plugstack.c:


/*
* Do not load static plugin options table in allocator context.
*/
if (stack->type != S_TYPE_ALLOCATOR)
plugin->opts = plugin_get_sym(p, "spank_options");


In the ALLOCATOR context you must register any CLI options using spank_options_register() inside your slurm_spank_init(). See e.g.


https://github.com/jtfrey/ud_slurm_addons/blob/master/spank/gridengine_compat.c


and the slurm_spank_init() function therein. The documentation page doesn't mention the fact that if you named your option list "spank_options" the plugin loader will automatically register them in non-ALLOCATOR contexts.
