Issue To Be Solved

We should add the cadence 1.0 update checker to the staging contracts command.

This could be a preflight check to ensure that there is some basic level of compliance with Cadence V1.0 update rules before somebody stages to the network. It could prevent friction where developers stage contracts, later find out from external analysis that this is invalid, have to repeat process. The idea is to catch obvious errors where somebody makes an incompatible update.

(Optional): Suggest A Solution

Add this check but make it optional. It should not block users from staging entirely as outlined in Discord.
