Cannot instantiate QgsFeatureFilterModel using PyQGIS

[DavidPavlicek]

When I try to create new instance of QgsFeatureFilterModel using Python (plugin or in console) i get this:

>>>model = QgsFeatureFilterModel()
Traceback (most recent call last):
  File "C:\PROGRA~1\QGIS3~1.18\apps\Python37\lib\code.py", line 90, in runcode
    exec(code, self.locals)
  File "<input>", line 1, in <module>
TypeError: qgis._core.QgsFeatureFilterModel represents a C++ abstract class and cannot be instantiated

It works flawlessly in QGIS 3.12. Starts to complain after upgrade to 3.14
