specifying :pathname arguments to ASDF components as strings had NEVER
been working portably before ASDF 1.630. The current behavior might
not fit all the non-portable expectations that someone or some other
might have fancied at some point, but 1- it is now portable, and 2-
any previous non-portable expectation can still achieved with a simple
#p prefix to your namestring. Therefore, I think the current behavior
is 100% better than the previous one. It indeed needs to be better
documented, though.

It would be nice if from your file was extracted a test for the actually
supported combinations. I'd include that in the ASDF test suite.
As for the non-supported combinations, well, they are not supported,
never have been, and probably never will.

Note interestingly that #p"..." pathnames other than logical pathnames
are not portable either, are not supported, and should NOT be tested
in the test-suite.

Not supported. Never will be. Please use #p for that.

Can you give an example?

If you can produce a list of failures in cases that should be
supported, that'd be great.
