Question Access Components in Trigger/Collision Jobs

Is there a (better) way to access components inside ITriggerEventsJob/ICollisionEventsJob than having this:

Code (CSharp):

1. public partial struct EffectsTriggerSystem : ISystem
2. {
3. [ReadOnly] private ComponentLookup<Parent> _lookupParent;
4. [ReadOnly] private ComponentLookup<PowerUpData> _lookupPowerUp;
5. [ReadOnly] private ComponentLookup<EffectSpeed> _lookupEffectSpeed;
6. [ReadOnly] private ComponentLookup<EffectDamage> _lookupEffectDamage;
7. [ReadOnly] private ComponentLookup<EffectBoostXP> _lookupEffectXPBoost;
8. [ReadOnly] private ComponentLookup<EffectRegenHP> _lookupEffectRegenHP;
9. [ReadOnly] private ComponentLookup<EffectRegenArmor> _lookupEffectRegenArmor;
10. [ReadOnly] private ComponentLookup<EffectShield> _lookupEffectShield;

Can I work with Triggers inside ISystem/SystemBase without a job?
Is this approach not-too-much-worse performance-wise (having generic System and Job):

Code (CSharp):

1. public partial struct EffectTriggerSystem<T> : ISystem where T: unmanaged, IEffectTimed
2. {
3.    [ReadOnly] private ComponentLookup<Parent> _lookupParent;
4.    [ReadOnly] private ComponentLookup<PowerUpData> _lookupPowerUp;
5.    [ReadOnly] private ComponentLookup<T> _lookupEffect;
6. ...
