Sean Owen commented on SPARK-18278:
-----------------------------------

Generally, ASF projects produce source not binaries, but, certainly also 
publish binary artifacts as a convenience. A docker image falls into that 
category. The drawback -- and it's really not trivial -- is that it means we 
are distributing a bunch more third party software and now have to police the 
license of everything in that image. That alone may be a deal breaker depending 
on what exact bits must be distributed.

Aside from that the question is maintenance burden vs convenience for users. I 
think ASF projects don't generally distribute 'packagings' but do distribute 
binary forms of source artifacts. For example, Spark doesn't publish RPMs or VM 
images.
