If by "the code above" you mean your original patch and my merge
thereof, then yes it is the same, with just a tiny bit of refactoring.
If by "the code above" you mean Robert's version with #+ecl, then no,
it's different, since Robert's version resolves the features at
read-time; by the time the features are updated, it's then too late
for ASDF to change its mind.
