Proposal

The following CSS variables are not referenced in bootstrap-reboot*.css but are included in compiled assets.

They doubled the download size (6187 out of 12065 characters are CSS variables) with no real benefits. Maybe consider removing them in v6?

Hi @manviyadu1shi I'm off for a few weeks so sorry for the quick answer. As mentioned in our contributing guidelines we don't assign issues. Moreover, this one is labeled as v6 so it can't be started now as the v6 dev hasn't started yet.
