I already replied to all your questions on c.l.l but I'll reply again here.

Because it's not used solely by ASDF, but also by XCVB.

It is still supported by ASDF2 and will remain supported for ASDF2.
But yes, we recommend new users to move to the new way.
You can still select sources with the new way,
e.g. using :directory instead of :tree.

3a- Use #.

3b- A future version will use the path designator DSL from
output-translations in the source-registry, at which point you can
specify (:home "share/common-lisp/systems/")

:current-directory was removed as non sensical on many Lisp implementations.

Try this entry:
((:home "Science/Source/Common Lisp/")
 (:home "Science/Source/Common Lisp/" #p"**" :implementation #p"*.*"))

I'm not sure what you mean, so I'd say probably not.
If you have "black magick" that you think should be part of ASDF,
please submit it here, and/or as an ASDF bug on launchpad.
