    Hello,

    But users would love to have something like 'qt6-full-dev'. And the
    reason we never provided them with this meta-package is that package maintainers would use it almost everywhere, dragging the whole Qt installation on each package depending on it... This is a _huge_ waste
    of resources and buildd time (or is it not??)

    It is, but also on maintainer systems when testing in bare chroots etc.
    So I don't think maintainers would use it that much in practice.
    (similarly to no package currently build-depending on texlive-full)

    So, what about if we could have [meta] packages that can be installed by
    the user but not used as Build-Depends entries? Please note that for the moment I'm targeting more at the idea itself rather than at the implementation (but I'll certainly love to know if you have an idea on
    how could this be implemented).

    At one point I thought of adding a Lintian test checking for this kind
    of usage, but first and foremost I would like to know if you think this
    is a viable/acceptable idea, maybe even adding a special section in our policy.

    I could have sworn that we already had tags like that in Lintian.
    Certainly, this is a concept that has already existed in Debian for some
    time. There have always been metapackages or other similar cases that are
    only intended for end users and would make no sense as build dependencies,
    such as all of the task-* packages.

    Lintian feels like the right place to put a test like this. If there are dependencies like that which could potentially cause serious issues, those could even be an auto-reject tag.

    I'm not sure that Policy would have much to say about this unless we need
    some mechanism for labeling such packages other than a MR to Lintian. The important information is the list of packages that shouldn't be used this
    way, and the hard part is probably gathering that list.

    I think it would be better to use social methods to prevent maintainers
    from doing this, rather than technical ones.

    I like the idea of a Lintian check, assuming Lintian accepts checks
    which don't correspond to Policy. I'm not sure it makes sense to try
    and encode this restriction in Policy itself.


    Best wishes,
