Additional context: Sylius/Sylius#8392
In Sylius a PR of mine moved the app from using Twig 1.x to Twig 2.x, in that PR I removed all uses of deprecated/compatibility methods and interfaces from the ThemeFilesystemLoader that they have. Apparently doing so causes the undefined method error in the linked Sylius issue report.
Would it be possible (or practical) to make the TemplateManager be able to work without requiring the compatibility interfaces?
