#457 (comment)

This PR was correct AFAIK, the configure delete should not be required with self.info.clear() in package_id

[SpaceIm]

IMHO, options which are not used at all should be removed in configure() not package_id().
Options which are used in build(), package() etc but don't change package id should be removed in package_id().

When header_only=True, shared option doesn't make sense anymore, it has not effect and therefore should be removed in configure(). It's not like a convenient option which for example enable a verbose build or something like this, but lead to the same package artifacts, this option changes what happens during the build (but end result is the same).

So for me no this PR was not correct by allowing illformed recipes.
