That's fine, of course. I only object to the ASDF 2 documentation seemingly promoting a particular approach for which there is not necessarily a community-wide consensus that it's the best one under all circumstances.
Logical pathnames are not recommended because there is no documentation on how to use them. If you want them to be more supported than they are, you pretty much will have to support them yourself.
Please write the documentation on how to use them, and then commit to answering the questions of newbies who'll try to use them. Having little experience with them, except to get rid of them when James Anderson tried to introduce them in a large project where they couldn't fit, I am unfit to provide this support.
