the feature is that <version>1.12.2-2838-7.2.2</version>
is linked to the forge 1.12.2 version that ends with 2838
another option would be to display spongeForge in the Forge section as another forge release
as Forge always shows build 0 we could list the version from the Json instead to correlate
as you can see I'm on Commit 75f55d2 and when viewing Branch:master mineos/profiles.js [ 5735c42 ] it lists SpongeVanilla
That is not displayed, nor is SpongeForge @ https://repo.spongepowered.org/maven/org/spongepowered/spongeforge/maven-metadata.xml SpongeAPI @ https://repo.spongepowered.org/maven/org/spongepowered/spongeapi/maven-metadata.xml
