I proposed to use libcurl-minimal and curl-minimal in minimal base images
half a year ago but there has been no reply so far:

If a package (strictly) requires libcurl-full, it should probably have an
explicit dependency for it. If some packages require implementation of a
specific protocol or feature, we could introduce virtual provides for them,
too, to make the sets of protocols/features in the -minimal variants less
hard-coded.

This is more a question for users of (lib)curl. I do not have any strong
opinion on that.
