This is an optional dependency. It won't be added as direct requirement.

You got same answer in laminas/laminas-validator#220

We no longer allow optional dependencies to be added, however they would remain optional until they removed by a next major release.

This error still exists.

That doesn't mean that this bug needs to be fixed immediately. But in fact it is an error that is documented here.

Disagree: while optional dependencies are indeed problematic, they are not bugs per-se, and rather require manual intervention.

Analyzing vendor/ code out of context is still a mistake, since you may even get random test assets in there, so be careful about your assumptions: this is NOT a bug.

They are a concept of the past: we got rid of them from new code, but there's no easy way around this.

The usage of such code with optional dependencies requires additional steps that are not "out of the box", and that is OK-ish, especially when compared with introducing BC breaks.

I will reopen it as an improvement to track for next major.
