Is OData no longer supporting Query Folding?

Here's an example for Salesforce Objects

let
    Source = Salesforce.Data("https://login.salesforce.com/", [ApiVersion=48]),
    Account1 = Source{[Name="Account"]}[Data],
    #"Filtered Rows" = Table.SelectRows(Account1, each Date.IsInPreviousNDays([CreatedDate], 30))
in
    #"Filtered Rows"

This query allegedly doesn't fold

Running the diagnostics however reveals that it does indeed fold into custom SOQL. Check the "Data Source Query"  column.
