I was wondering if it would be possible to make beds only contribute to settlement happiness, not determine it. In other words, say there are five settlers in a settlement, you only need five beds, but you do NOT have to assign them to it. This would eliminate the issue of settlers unassigning themselves to beds and creating the oh so infamous "people are complaining about the beds issue". Furthermore, you could make a little joke against bethesda where the more unnecessary beds there are, the more happy settlers are, just as a little satirical mockery :P.
