I think in symfony/symfony packages, we don't use suggest but here, if it helps someone, I think it's ok.

[dbu]

yeah i wondered and saw symfony/symfony is not using them. imho it would be helpful here, especially the http-client which will probably be needed for a good part of the users.

I'm not sure to remember the reason ... maybe @kbond @weaverryan or @nicolas-grekas ?

In all manner we won't change this for a single repository, so the question is more "do we want to add composer suggest to UX packages"

We could also add http-client contracts here and throw at runtime if no concrete implementation is available ?

[nicolas-grekas]

We don't use that because it's just noise. composer won't display suggestions by default anymore for this reason. Every packages can add stuff there and this is a mess very quickly.

BTW: composer/composer#12354

[dbu]

composer won't display suggestions by default anymore

i was not aware of that. then imho lets drop this. i let you close it, in case there is still need for some discussion.

Ah ok, I wasn't aware of the reason. TIL
