No, port DIR names become arbitrary. From what I understand the only reason 
they are not supposed to be arbitrary right now is because of the portdir name 
= port name assumption that is currently still required to avoid reindexing. 
There is no other side-effect of using a deviant portdir that I've been able to 
observe.
If you ask me, the choice not to include the parent directory (and the 
category) in the indexing feature is just as arbitrary, yet lint does complain 
about a main category/dirname mismatch IIRC.

And what's wrong with arbitrary portdir names as long as there is a minimum of 
common sense in their naming? I don't think anyone would chose a truly 
arbitrary and non-informative name for the directory in which they store their 
port files. It is true that for the vast majority of users, the portdir name is 
without any interest, maybe even for most port developers/maintainers. On the 
other hand, for those of the latter who maintain/develop lots of ports, there 
is an advantage in being able to organise the port tree the way that works best 
for them (= most efficiently).

Take port:kde-extra-cmake-modules. The port was called that way mostly to make 
its nature clear to those who find it gets pulled in when installing something, 
and to avoid naming conflicts with potential other ports that install extra 
modules for cmake. KDE (build) code refers to it as ECM, however, so `kde/ECM` 
works much better when you have to refer to its port implementation from time 
to time than `kde/kde-extra-cmake-modules` . Similarly, if you maintain a 
growing but already large number of ports for KF5 packages, you can get around 
in the port tree much more easily if all those port directories do not all have 
a name that starts the same. Be it if you work with an IDE like I do (and thus 
have the limited width of the filesystem tree navigator to deal with) , through 
a Finder window or even with completion in a terminal, all information that is 
redundant (to the "user", because already available elsewhere) and repeated 
adds an additional attentional load.

not hard to see in which one it's easier to select just about any target, right?

It would be a bit different if it were usual to use a suffix (foo-kf5) rather 
than a prefix (kf5-foo). I've also considered developing on what could have 
been a numbering scheme (port:kdelibs4 -> port:kdelibs5) but that isn't natural 
because it wouldn't correspond to the naming of what is being installed (and 
there is no such thing as kdelibs in KF5).
