Do we have the system dependencies right yet?

I was just looking at one of my systems that has a kind of system
dependency that won't work in ASDF2 any better than ASDF Classic.

Here's what we have:  a large piece of software with many ASDF entry
points.  I.e., there are many .asd files which could be loaded at the
top level.  E.g., SYS-FOO, SYS-BAR, SYS-BAZ, ...

We want all of these systems to have a common :VERSION.

What this means is all of our .ASD files have this at their head:

(asdf:oos 'asdf:load-op :SYS-VERSION)

(defsystem SYS-FOO
  :version #.sys-version:+version+
  ...)

Unfortunately, our ASDF-LOAD of the SYS-VERSION system, which just
defines a package and a constant, cannot be replaced by
:system-dependencies ...

This is effectively the same problem that James Anderson pointed out
some time ago, but that I didn't yet appreciate.

Do we ship with system-dependencies or try to come up with something
better before shipping asdf 2.0?

best,
