After updating to 4.3 I started receiving a bunch of deprecations:
 - `Enabling the Templating component is deprecated since version 4.3 and will be removed in 5.0; use Twig instead.`
 - `The "templating.cache_warmer.template_paths" service is deprecated since Symfony 4.3 and will be removed in 5.0.`
 - `The Symfony\Bundle\FrameworkBundle\CacheWarmer\TemplatePathsCacheWarmer class is deprecated since version 4.3 and will be removed in 5.0; use Twig instead.`
 - `The "templating.finder" service is deprecated since Symfony 4.3 and will be removed in 5.0.`
 - `The "templating.locator" service is deprecated since Symfony 4.3 and will be removed in 5.0.`

The main gist here was _"use Twig instead"_, which I'm already doing. Hopefully the changed messages in the upgrade guides/config should guide developers to the solution, as it seems to be as simple as removing the config to prevent all these deprecations from triggering. After removing the templating config, it fixed all these deprecations for me without breaking anything else (from what I could tell).
