Magento 2.4.3 + Redis(7?)

In my test environment (Ubuntu 20.04, PHP7.4, Percona 8.0, Varnish 6.5) I’ve just installed redis (backend, page cache and sessions) without thinking much about its version. And of course it’s of version 7.02. I know Magento 2.4.3 requires Redis 6.0 but I haven’t noted any problems with version 7.02. Does anybody has any experience running Magento 2.4.3 with Redis 7.0 in live environment under heavier load?
