They try somewhat to warn what will break in future releases. So you get a few releases of warnings and then a release of THIS WILL BREAK NEXT RELEASE and then it breaks. One thing for PHP is a huge 'customer' is the Wordpress universe and they have been good about not breaking Wordpress. But with PHP 8 that will change. If you are on PHP4 and are moving to the 7.x series plan for some pain. My problem is I try to find things that will work with flat files. I just spent some time moving from Mediawiki to PMwiki, because of the database nonsense in keeping that in sync with PHP and Mediawiki. I'd love to find a CRM tool that had the flexibility shown here but would live in flat files that I may have a chance to import into something else.
