Comment (by Ionic):

 I've now downgraded base to 2.5.0, 2.4.4, 2.3.5 and they all behaved the
 same (i.e., tried to upgrade `OpenBLAS` directly instead of working on any
 dependencies).

 However, 2.2.1 behaves differently. Not exactly like I would like to have
 it, but still better. A dry run would have rebuilt at least `cctools` and
 `llvm-3.7` due to changes in the `universal` variant (both ports are
 currently installed `-universal`), so that's a start. The dry run did not
 reveal a `libgcc9` rebuild, though.

 So there was definitely a behavioral change from 2.2.1 to 2.3.5 at least,
 but it's still not quite the one I was looking for. I'll try to go back
 even further (if possible).
