An alternative feature doesn't necessarily need to be compatible with a previous feature. #slip39 is an alternative to #bip39. It offers more and flexible #backup possibilities for the #security focussed #bitcoin user. Everything you surely already know. #trezor did implement #slip39 even though it is incompatible with #bip39. No plans for #coinkite to extend #coldcard #backup features by #slip39 or #sskr ?
