Sure, it's worth considering, but for most companies it's not going to be worth the engineering effort to architect cross-cloud services. The complexity is NOT linear.
IMO most shops should focus on testing backups (which should be at least cross-cloud, potentially on-prem of some sort) to make sure their data integrity is solid. Your data can't be recreated, everything else can be rebuilt even if it takes a long time.
