It's no big deal to support

   keyword={{a, b, c}},

which then gives:

   <pdf:Keywords>a, b, c</pdf:Keywords>

but then you end up with

   keyword={{a, b, c},{d, e, d}},

becoming

   <pdf:Keywords>a, b, c d, e, f</pdf:Keywords>

i wonder what, after encountering this, the next request will be ...

anyway, I suppose you will check what different viewers make of that 
when they display/handle keywords and wikify it
