Right now only gocryptfs and Cryfs are supported, but as Vaults is, having more options could be amazing, for example eCryptfs and cryptomator encryption.
Both are licensed under GPL (v2 and v3), so shouldn't have problems for that, actually, cryptomator is so used in cloud encryption, so vaults could be a great frontend.
Veracrypt vaults could be amazing too, but the license is not libre (as FSF say), but its open source (is accepted by the OSI).
