Should configuration and fixture files be accepted with the `.yml.erb` extension?

I’ve made a PR to have test fixture files ending in .yml.erb get picked up by ActiveRecord.

My motivation behind this was that

  1. I was surprised when given that .html.erb/.js.erb/.xml.erb files are picked up inside app/views, my foo.yml.erb file wasn’t picked up inside test/fixtures
  2. My text editor, Vim, didn’t apply the correct syntax highlighting for the ERB syntax unless the file extension ended in .erb

However as Petrik de Heus pointed out, this adds more complexity. What should be the proper behaviour here?
