While having support for Lightroom proprietary format and edits would be a nice way for existing photographers that are vendor locked into Adobes software it is a Herculean effort for very little real benefit. The photographers that were lulled into "live lossless edits" with (the free for ever beta of) Lightroom already made the choice to be hamstrung by and having their edit being locked into Adobes format. They should accept the loss and render exported versions of their edited images. It is a fact that XML sidecar edits are not portable or suitable for archiving.
