Description

Right now the only one option to use helpers inside blocks - is following code:
$this->helper(<helper_class>), but this Magento2.Templates.ThisInTemplate rule complains against it. As result - we have to add to ignore Magento2.Templates.ThisInTemplate in many view files.

Examples:
Try to find "Magento2.Templates.ThisInTemplate" in following commit:
magento/magento2@514e3d0

Expected behavior

We should not have any complains from static tests when running valid code

Benefits

We will not have useless disabling of this rule

Additional information

Option 1: this code example should be added to exception list
Option 2: there should be developed or provided recommended solution how to avoid it
