If your node definitions contain only class and maybe variable declarations -- a good practice -- then you would not have much trouble doing the same thing with an ENC. With that said, I don't think there are very many sites that would benefit from *writing their own* ENCs. If you are using Foreman or the Puppet Dashboard, however, then you already have an ENC available to you, with a spiffy UI and everything. Overall, as long as you're satisfied with writing node definitions in Puppet DSL, I don't think it's worth the time and effort to change.
