EntityQueryDesc component types always have readwrite permission

It seems like even though I specify ComponentTypes as ReadOnly in EntityQueryDesc definition, it still gets converted to ReadWrite permission. (Entities version: preview 33 - 0.0.12 in EntityGroupManager.CalculateRequiredComponentsFromQuery() line: 381 )
Is that the correct behaviour?

I would like to use the EntityQueryDesc with a None filter, but using this way all of the components will be marked as changed.
If I use IJobForEachWithEntity with ExcludeComponent I get the desired behaviour. But in my case I cant use IJobForEachWithEntity for this query.

Edit: Updated picture to show the workaround to this issue.

Looks like there is a way to solve this issue.
I can just use GetEntityQuery with ComponentType[ ] override and than use the ComponentType.Exclude() version, to skip unwanted components.
That will use EntityGroupManager.CreateQuery(ref ScratchAllocator scratchAllocator, EntityQueryDesc[ ] queryDesc) override under the hood, which will correctly set up ReadOnly permissions.

Yeah I can confirm the same bug.

Creating an EntityQuery with EntityQueryDesc does not respect ReadOnly restrictions

Coincidently noticed this yesterday as well. It’s not always the case but seems to pop up when getting query from a cache or something.

Did this ever get fixed in entities 0.50?
