If the soft dependency is indeed completely optional, t= he software
works perfectly fine without it and= few people will be negatively
impacted by a mi= nor feature missing, then it's fine to leave it as-is

This is the only point I'm making=2E Things like templates and e= ncryption aren't used by everyone so could definitely be optional, so I was= asking if there was a simple way to handle optional inputs=2E As it doesn'= t seem like there is I'll just add everything required=2E
