Just make an if condition so that this tackles UploadBreadcrumbs

Model-specific order_by fix could apply to all models
Low Severity
The order_by() optimization is hardcoded only for UploadBreadcrumb, but ordering is never needed when materializing IDs for IN filters. Other models also have Meta.ordering (e.g., Repository has ordering = ["-repoid"]) and would benefit from the same treatment. The conditional if queryset.model == UploadBreadcrumb could simply be removed so queryset = queryset.order_by() applies unconditionally, avoiding the same sequential-scan risk for any model with default ordering — and eliminating a model-specific special case from a generic function.

Might be worth following this suggestion if it's an improvement, though I'd prompt AI first to see if all other models would benefit from this, cause some could be hindered


this should help with the sequential scan on the uploadbread crumb table
Legal Boilerplate
Look, I get it. The entity doing business as "Sentry" was incorporated in the State of Delaware in 2015 as Functional Software, Inc. In 2022 this entity acquired Codecov and as result Sentry is going to need some rights from me in order to utilize my contributions in this PR. So here's the deal: I retain all rights, title and interest in and to my contributions, and by keeping this boilerplate intact I confirm that Sentry can use, modify, copy, and redistribute my contributions, under Sentry's choice of terms.
