Dear Nicole,
Of course there are challenges involved, like needing bleeding edge packages [and any problems] will stay the same and next release there will be other newer packages we need for $SOMETHING. So also here, better try to come up with an acceptable solution now.
Thank you for sharing this but moreover happening to elucidate my own position so clearly — this, at the very least, will push off my inevitable RSI by another hour or so into the future...
However, we need not phrase it quite so "practically" and with a tone of resigned regret - we will not be the only distribution who will be basing ourselves on buster and making non-trivial backports etc. :)
Best wishes,
