Proposal: Remove restriction to only allow event triggers in FrameworkElement.Triggers collection

[SetTrend]

Current Situation

Currently, property triggers are only available by takting the detour using the FrameworkElement.Style property and its Style.Triggers collection. Assigning a property trigger immediately to the FrameworkElement.Triggers collection raises an error.

This restriction makes no sense and is a quirk that's repeatedly causing confusion and unneccessary ado.

Desired Situation

I propose to remove the current artificial restriction for the FrameworkElement.Triggers collection that's constraining it to only accept event triggers and to harmonize the FrameworkElement.Triggers collection's feature set with the Style.Triggers feature set.
