I'm often running into the situation where the validation failed either due to transient circumstances in the org, or due to the org settings being incorrectly configured. In this scenario, I would like to simply retry the validation using the same package, and I'd look for that option somewhere here:

Running a new comparison (using the "clone package" option) is unnecessary, takes a lot of time. Also using the "view comparison" option is overkill. I would rather not go through those motions of recalling the comparison results from cache, going through the analysis once again, etc. Because I know those steps to be unnecessary.

Instead, it would be super convenient with a retry button on the "validated packages" page, that simply runs the validation again using the saved package.

The same goes for failed deployments. Sometimes things do fail due to transient/temporary issues, or incorrectly configured org settings etc, in which case it makes most sense to retry using the same package.
