Unable to save Page that was inherited from Wagtail Page but doesn't registered with modeltranslation

I have an application blog that have two Models:

1. BlogIndexPage(Page) that registered with modeltranslation.decorators.register at translation.py
2. BlogPage(Page) - doesn't have versions for different languages. And doesn't registered with decorator. Each blog post will have own language and sometimes will never translated to any other languages. Or will translated by another author.

I got an issue that I'm not able to save BlogPage at wagtail because title is required.

Seems the problem related to patching Page at here:

wagtail-modeltranslation/wagtail_modeltranslation/translation.py

Lines 8 to 9 in 21fa6f9

	@register(Page)
	class PageTR(TranslationOptions):

In my opinion it should be opportunity to inherit from wagtail.models.Page both type of pages that should be translated that doesn't required translations.
