Considering that SBCL upgraded to 3.1.5 in July 2015, I think you should be pretty safe assuming that your users' ASDF is more recent than 3.1.4.
What more, even Xach seems to have miraculously seen the light: one months and one week ago, he updated the fallback ASDF in Quicklisp from 2.26 to 3.2.1! That was the first update of ASDF in Quicklisp since 2012, to a version then-current, to a version 4 years old. By linear extrapolation, we should expect the next update to happen in 2030, to a version from 2022. I admit that I was thinking his next move would be to downgrade ASDF to 1.369 (the last version before I took over).
Didn't he revert that change after something broke?
