Any chance of an older version of MC v1.14.4 getting released (like Forge v28.049+)? Most people/mods haven't made the switch to Forge v28.1.0, because Forge updates almost every day.

So when new mods come out specifically only for the most current version of Forge, it makes it impossible to try, without removing all other mods.

No, sorry. This mod depends on some of the fixes to forge since 28.0.49. Ask those devs to update past broken beta versions of forge.
