I think it would still be cheap to add those fields.
Compare the normal jobs/:id route:
SELECT me.id, me.result_dir, me.archived, me.state, me.priority, me.result, me.reason, me.clone_id, me.blocked_by_id, me.TEST, me.DISTRI, me.VERSION, me.FLAVOR, me.ARCH, me.BUILD, me.MACHINE, me.group_id, me.assigned_worker_id, me.t_started, me.t_finished, me.logs_present, me.passed_module_count, me.failed_module_count, me.softfailed_module_count, me.skipped_module_count, me.externally_skipped_module_count, me.scheduled_product_id, me.result_size, me.t_created, me.t_updated, settings.id, settings.key, settings.value, settings.job_id, settings.t_created, settings.t_updated FROM jobs me LEFT JOIN job_settings settings ON settings.job_id = me.id WHERE ( me.id = ? ) ORDER BY me.id: '3180131'
SELECT me.id, me.result_dir, me.archived, me.state, me.priority, me.result, me.reason, me.clone_id, me.blocked_by_id, me.TEST, me.DISTRI, me.VERSION, me.FLAVOR, me.ARCH, me.BUILD, me.MACHINE, me.group_id, me.assigned_worker_id, me.t_started, me.t_finished, me.logs_present, me.passed_module_count, me.failed_module_count, me.softfailed_module_count, me.skipped_module_count, me.externally_skipped_module_count, me.scheduled_product_id, me.result_size, me.t_created, me.t_updated FROM jobs me WHERE ( me.clone_id = ? ): '3180131'
SELECT me.job_id, me.asset_id, me.created_by, me.t_created, me.t_updated FROM jobs_assets me WHERE ( me.job_id = ? ): '3180131'
SELECT me.id, me.type, me.name, me.size, me.checksum, me.last_use_job_id, me.fixed, me.t_created, me.t_updated FROM assets me WHERE ( me.id = ? ): '66876051'
SELECT me.child_job_id, me.parent_job_id, me.dependency FROM job_dependencies me WHERE ( me.child_job_id = ? ): '3180131'
SELECT me.child_job_id, me.parent_job_id, me.dependency FROM job_dependencies me WHERE ( me.parent_job_id = ? ): '3180131'
which does 6 SELECTs, to the current status route:
SELECT me.id, me.result_dir, me.archived, me.state, me.priority, me.result, me.reason, me.clone_id, me.blocked_by_id, me.TEST, me.DISTRI, me.VERSION, me.FLAVOR, me.ARCH, me.BUILD, me.MACHINE, me.group_id, me.assigned_worker_id, me.t_started, me.t_finished, me.logs_present, me.passed_module_count, me.failed_module_count, me.softfailed_module_count, me.skipped_module_count, me.externally_skipped_module_count, me.scheduled_product_id, me.result_size, me.t_created, me.t_updated FROM jobs me WHERE ( me.id = ? ): '3180131'
And now looking at that, that seems even wrong.
When I added that route, I only did a select on 4 fields. But later it was changed to select all fields, but only return those 4 fields in JSON :(
And it was actually me who did that change. That should be easy to fix.
