batches don't work well with ActiveJobs

[pirj]

From toptal#9

Avoid using self-scheduling jobs for long-running jobs. Prefer using Sidekiq Batches to split the workload.

is misleading, because:

Batches break if you use Active Job’s retry_on feature. Since that is quite common, I recommend against using AJ for batches.

toptal#9 (comment)

This guideline needs to be adjusted to avoid those who do use Active Job on top of Sidekiq from using Sidekiq Batches.

Q: How does maintenance_tasks do batches with Active Job?
Do they use their job-iteration underneath?
Would it be reasonable to recommend it when ActiveJob is used on top of Sidekiq?
Sidekiq batches still make sense when using Sidekiq directly.
