I like those aims too but there is one rather big problem in the way;
who is going to pay for that decidedly non-trivial amount of work?
To make 'everything that is available works with the current '
requires the owners of every package to promptly update their code
with every release, and to maintain it so that either the one version
works with all those previous release or to maintain several
versions. That's a lot of work for many people.
Of course, if these are really important matters to your business
then perhaps your business plan should include paying a few people to
do some of the work needed to achieve them? We did a fair bit of
that at Interval, exobox and now, Sophie.
