And what is the guarantee that a no-longer-maintained dependency will have a suitable and exact alternative? Also, tests catching breakage doesn't solve the breakage, so regular upgrades can be quite time consuming, From my experience, dependencies introduce complexity in a super-linear manner, and one should be very careful in introducing them. This is a general principle that goes beyond NPM.
