This wasn't a constructive feedback unfortunately and more a feeling
than a measurable criticism. To actually improve the state, maybe first
check what helpers are actually there, how they are used and if they are
suitable to what they are used for.

Having many helpers is a hint that the usage is complicated. Is that
because the situation is complicated, or is this just a big pile of
inconsistency that can be simplified and consolidated?

Also I think there are helpers that take a resource type parameter (as
your function) and others hard code it in the function name. Maybe
unifying that would be nice, too.

Best regards
Uwe
