Hello @mtrezza
Do you plan to also remove all the type conversions in the pipeline? (the _parseAggregateArgs method basically).
It's a real mess to write aggregation with Parse, as some fields are converted and others are not, some are wrongly converted, some are removed, etc.
Dates fields are very messy too.

This issue is just removing the deprecation; see #7338 and #7339 for the full scope of the deprecation.

I think you are referring to #7868. That's a separate issue and currently without an ETA. There is an existing PR #8172, but it's still WIP.

[SebC99]

True, thanks.
Except #7868 should be broader as there are server crash issues but also wrong results ones as you the pipeline is modified under the hood. I'll try to look into #8172 .
