https://symfony.com/doc/5.4/reference/dic_tags.html#kernel-reset

During the kernel.terminate event, Symfony looks for any service tagged with the kernel.reset tag to reinitialize their state. This is done by calling to the method whose name is configured in the method argument of the tag.

If you will check the codebase about services_resetter (main service with all known services tagged as kernel.reset) callers - you will find, that it is called only on kernel 2+ booting (if we talking about HTTP context)

Should the documentation be updated about the moment, when reset method will be called?
