Packages abandoned you should avoid using it

Hi,
Installing Sylius for the first time, when running composer I got these warnings :

Package container-interop/container-interop is abandoned, you should avoid using it. Use psr/container instead.
Package phpunit/phpunit-mock-objects is abandoned, you should avoid using it. No replacement was suggested.
Package symplify/better-phpdoc-parser is abandoned, you should avoid using it. Use rector/rector instead.
Package symplify/token-runner is abandoned, you should avoid using it. Use https://github.com/symplify/codingstandard instead.

Should I ignore them ?
