How important is the php-mysql module for 1C Bitrix?

Question

PHP

Bitrix has a script for checking server settings . So he says that the mysql module is needed.
As you know, it was cut out of php 7+ versions.
Are they stuck in the past or is this information not relevant?

Answer 1

I think the script is just out of date.
Its first lines:
Work with mysqli has been supported for a long time.

Answer 2

nonsense, I have all the bitrixes on the seven
and your script is about nothing
