While there is nothing wrong with hard-coding certain exclusions (e.g. players, and anything that's neither a mob nor a projectile), having the exclusion list in a configuration entry makes it nearly impossible for other mods to opt out of the interdiction effect by default.

For example, Botania's mana bursts are projectiles and there are frequent questions why spreaders don't seem to fill mana pools. The root cause is almost always either Optifine (it just breaks things) or interdiction torches. It would be great if Botania could simply add its mana burst entity to a particular entity tag (e.g. something like #reliquary:interdiction_excluded) to have the two things "just work" together, out of the box.
