To make it clear, these permutations will probably never be supported for 2 reasons:

* We will have to provide all versions of all runtimes in all VM images. Ruby VM image is already at 3.1 GB, adding all Node, PHP, OTP and soon JDK versions to it is not an option.
* Travis builders assume one primary runtime you switch and permutate with env variables, gemfiles and so on. This works well for 99% of projects.
