The documentation page you’re referring to already warns about it:

“To use the ObjectNormalizer, the PropertyAccess component must also be
installed.”

This is intended upstream, that only suggests symfony/property-info in
their composer.json file.

https://github.com/symfony/symfony/blob/master/src/Symfony/Component/Serializer/composer.json

Composer documents suggest as follow:

Suggested packages that can enhance or work well with this package. These are
just informational and are displayed after the package is installed, to give
your users a hint that they could add more packages, even though they are not
strictly required.

https://getcomposer.org/doc/04-schema.md#suggest

Debian documents suggests as follow:

This is used to declare that one package may be more useful with one or
more others. Using this field tells the packaging system and the user
that the listed packages are related to this one and can perhaps enhance
its usefulness, but that installing this one without them is perfectly
reasonable.

https://www.debian.org/doc/debian-policy/ch-relationships.html#s-binarydeps

Both Composer and Debian interpretation of suggest seem to match well
enough, so if you believe the relation is too weak, you should try to
convince upstream about it.
