.. and probably many others
You cannot download releases of distributions that fit into these use cases:
1) have at least one sub module that is marked as 'not secure' / 'needs updating'
2) is an 'other' release
Steps To Reproduce
Visit a distributions project page
Cannot download a 7.x recommended release
PS, for some reason, commerce_kickstart does not link their modules in either the current d.o or the new one. Not sure why that is...
