Re: [infinispan-dev] Why JCache embedded has core as provided dependency

I would lean towards to removing them completely or limiting the number of use cases to the minimum e.g. we shouldn't support using infinispan-embedded and jcache; if jcache is essential it should be inside infinispan-embedded; the same for Spring integration modules - either we should put them in uber jars or say that you can use Spring integration with small jars.

I'm not trying to make an argument for keeping them, because I know they have caused many issues. I just think that if we are going to remove them from Maven, then there should be a way to achieve the same easy developer on boarding that uber jars were supposed to provide. Whether this is Maven project templates, or something else doesn't matter.
