Why was "compile with GHC too" reverted?

I'm about to use this package in a project based on the [reflex-project-skeleton](https://github.com/ElvishJerricco/reflex-project-skeleton).

So far, I've been developing using GHC via JSaddle and would hope to do so with this project as a dependency as well. However, the latest commit https://github.com/hexresearch/reflex-material-bootstrap/commit/0dbf56c743f9739b4e1ec7af8a47cdd3062f85f7 reverts an earlier change https://github.com/hexresearch/reflex-material-bootstrap/commit/0dbf56c743f9739b4e1ec7af8a47cdd3062f85f7 that enabled this.

What is the issue with the earlier commit ? I know it builds at least, as I've just successfully added this project as a dependency.

Is the issue anything that a contributor might be able to help with ?
