I tend to use a similar approach, though with Terraform var files instead of env vars. It was also possible to have this work with TF Cloud (and presumably Enterprise?) with a single workspace env var specifying the var file. It might have been improved recently to be a first class feature.

I found this to be my favourite workflow for managing workspace variables in a way that was also flexible to being run outside of TFC/TFE for when that makes sense.
