What I meant is that ASDF does not "understand" that 20201015 is a three-part version, whose first part is "2020" second is "10" and third is "15".

So note that my example is "any version since October 2020." And yours is "any version since October fifteenth 2020.

Why would ASDF not understand "version later than 20201015"?  I am perfectly fine with using the full 8 digit timestamp.

That's true, but possibly stating the obvious: ASDF does not
"understand" a version string like that.  So you can't say "any version
since October 2020 will work." Getting something like that to work would
be an exercise for the extension protocol.

This actually might make a good test case for us to see if the proposed
protocol (versioning method keyword initarg for defsystem) makes sense.
