There is a lot of insider information, spread mostly in forum posts like https://forum.polkadot.network/t/pallet-idea-safe-scheduler/1009 that the existing scheduler pallet is unsafe, and should only be used internally by the runtime. In other words, scheduling operations should not be allowed by arbitrary external users.

I am worried that, similar to offchain workers, this pallet it as first glance a silver bullet that might lead to someone designing an application with the wrong assumption, thinking that this pallet is going magically schedule things for them across blocks, while it won't, and it can easily lead a parachain to stall.

This information is vital and should be in the source docs of the pallet, not the heads of a few.

Additionally, a warning about the change of decoding for stored calls is also a good point to be mentioned.

Update https://paritytech.github.io/substrate/master/pallet_scheduler/index.html to be aligned with the house pallet documentation guidelines, and make sure this point is also covered.
